surveillance state encryption-backdoors Vance tyranny right-to-whisper

shared by Paul Merrell on 11 Dec 15 - No Cached
  • Less than a week after the attacks in Paris — while the public and policymakers were still reeling, and the investigation had barely gotten off the ground — Cy Vance, Manhattan’s District Attorney, released a policy paper calling for legislation requiring companies to provide the government with backdoor access to their smartphones and other mobile devices. This is the first concrete proposal of this type since September 2014, when FBI Director James Comey reignited the “Crypto Wars” in response to Apple’s and Google’s decisions to use default encryption on their smartphones. Though Comey seized on Apple’s and Google’s decisions to encrypt their devices by default, his concerns are primarily related to end-to-end encryption, which protects communications that are in transit. Vance’s proposal, on the other hand, is only concerned with device encryption, which protects data stored on phones. It is still unclear whether encryption played any role in the Paris attacks, though we do know that the attackers were using unencrypted SMS text messages on the night of the attack, and that some of them were even known to intelligence agencies and had previously been under surveillance. But regardless of whether encryption was used at some point during the planning of the attacks, as I lay out below, prohibiting companies from selling encrypted devices would not prevent criminals or terrorists from being able to access unbreakable encryption. Vance’s primary complaint is that Apple’s and Google’s decisions to provide their customers with more secure devices through encryption interferes with criminal investigations. He claims encryption prevents law enforcement from accessing stored data like iMessages, photos and videos, Internet search histories, and third party app data. He makes several arguments to justify his proposal to build backdoors into encrypted smartphones, but none of them hold water.
  • Before addressing the major privacy, security, and implementation concerns that his proposal raises, it is worth noting that while an increase in use of fully encrypted devices could interfere with some law enforcement investigations, it will help prevent far more crimes — especially smartphone theft, and the consequent potential for identity theft. According to Consumer Reports, in 2014 there were more than two million victims of smartphone theft, and nearly two-thirds of all smartphone users either took no steps to secure their phones or their data or failed to implement passcode access for their phones. Default encryption could reduce instances of theft because perpetrators would no longer be able to break into the phone to steal the data.
  • Vance argues that creating a weakness in encryption to allow law enforcement to access data stored on devices does not raise serious concerns for security and privacy, since in order to exploit the vulnerability one would need access to the actual device. He considers this an acceptable risk, claiming it would not be the same as creating a widespread vulnerability in encryption protecting communications in transit (like emails), and that it would be cheap and easy for companies to implement. But Vance seems to be underestimating the risks involved with his plan. It is increasingly important that smartphones and other devices are protected by the strongest encryption possible. Our devices and the apps on them contain astonishing amounts of personal information, so much that an unprecedented level of harm could be caused if a smartphone or device with an exploitable vulnerability is stolen, not least in the forms of identity fraud and credit card theft. We bank on our phones, and have access to credit card payments with services like Apple Pay. Our contact lists are stored on our phones, including phone numbers, emails, social media accounts, and addresses. Passwords are often stored on people’s phones. And phones and apps are often full of personal details about their lives, from food diaries to logs of favorite places to personal photographs. Symantec conducted a study, where the company spread 50 “lost” phones in public to see what people who picked up the phones would do with them. The company found that 95 percent of those people tried to access the phone, and while nearly 90 percent tried to access private information stored on the phone or in other private accounts such as banking services and email, only 50 percent attempted contacting the owner.

  • In addition to his weak reasoning for why it would be feasible to create backdoors to encrypted devices without creating undue security risks or harming privacy, Vance makes several flawed policy-based arguments in favor of his proposal. He argues that criminals benefit from devices that are protected by strong encryption. That may be true, but strong encryption is also a critical tool used by billions of average people around the world every day to protect their transactions, communications, and private information. Lawyers, doctors, and journalists rely on encryption to protect their clients, patients, and sources. Government officials, from the President to the directors of the NSA and FBI, and members of Congress, depend on strong encryption for cybersecurity and data security. There are far more innocent Americans who benefit from strong encryption than there are criminals who exploit it. Encryption is also essential to our economy. Device manufacturers could suffer major economic losses if they are prohibited from competing with foreign manufacturers who offer more secure devices. Encryption also protects major companies from corporate and nation-state espionage. As more daily business activities are done on smartphones and other devices, they may now hold highly proprietary or sensitive information. Those devices could be targeted even more than they are now if all that has to be done to access that information is to steal an employee’s smartphone and exploit a vulnerability the manufacturer was required to create.
  • Privacy is another concern that Vance dismisses too easily. Despite Vance’s arguments otherwise, building backdoors into device encryption undermines privacy. Our government does not impose a similar requirement in any other context. Police can enter homes with warrants, but there is no requirement that people record their conversations and interactions just in case they someday become useful in an investigation. The conversations that we once had through disposable letters and in-person conversations now happen over the Internet and on phones. Just because the medium has changed does not mean our right to privacy has.
  • Vance attempts to downplay this serious risk by asserting that anyone can use the “Find My Phone” or Android Device Manager services that allow owners to delete the data on their phones if stolen. However, this does not stand up to scrutiny. These services are effective only when an owner realizes their phone is missing and can take swift action on another computer or device. This delay ensures some period of vulnerability. Encryption, on the other hand, protects everyone immediately and always. Additionally, Vance argues that it is safer to build backdoors into encrypted devices than it is to do so for encrypted communications in transit. It is true that there is a difference in the threats posed by the two types of encryption backdoors that are being debated. However, some manner of widespread vulnerability will inevitably result from a backdoor to encrypted devices. Indeed, the NSA and GCHQ reportedly hacked into a database to obtain cell phone SIM card encryption keys in order defeat the security protecting users’ communications and activities and to conduct surveillance. Clearly, the reality is that the threat of such a breach, whether from a hacker or a nation state actor, is very real. Even if companies go the extra mile and create a different means of access for every phone, such as a separate access key for each phone, significant vulnerabilities will be created. It would still be possible for a malicious actor to gain access to the database containing those keys, which would enable them to defeat the encryption on any smartphone they took possession of. Additionally, the cost of implementation and maintenance of such a complex system could be high.
  • Vance also suggests that the US would be justified in creating such a requirement since other Western nations are contemplating requiring encryption backdoors as well. Regardless of whether other countries are debating similar proposals, we cannot afford a race to the bottom on cybersecurity. Heads of the intelligence community regularly warn that cybersecurity is the top threat to our national security. Strong encryption is our best defense against cyber threats, and following in the footsteps of other countries by weakening that critical tool would do incalculable harm. Furthermore, even if the US or other countries did implement such a proposal, criminals could gain access to devices with strong encryption through the black market. Thus, only innocent people would be negatively affected, and some of those innocent people might even become criminals simply by trying to protect their privacy by securing their data and devices. Finally, Vance argues that David Kaye, UN Special Rapporteur for Freedom of Expression and Opinion, supported the idea that court-ordered decryption doesn’t violate human rights, provided certain criteria are met, in his report on the topic. However, in the context of Vance’s proposal, this seems to conflate the concepts of court-ordered decryption and of government-mandated encryption backdoors. The Kaye report was unequivocal about the importance of encryption for free speech and human rights. The report concluded that:
  • States should promote strong encryption and anonymity. National laws should recognize that individuals are free to protect the privacy of their digital communications by using encryption technology and tools that allow anonymity online. … States should not restrict encryption and anonymity, which facilitate and often enable the rights to freedom of opinion and expression. Blanket prohibitions fail to be necessary and proportionate. States should avoid all measures that weaken the security that individuals may enjoy online, such as backdoors, weak encryption standards and key escrows. Additionally, the group of intelligence experts that was hand-picked by the President to issue a report and recommendations on surveillance and technology, concluded that: [R]egarding encryption, the U.S. Government should: (1) fully support and not undermine efforts to create encryption standards; (2) not in any way subvert, undermine, weaken, or make vulnerable generally available commercial software; and (3) increase the use of encryption and urge US companies to do so, in order to better protect data in transit, at rest, in the cloud, and in other storage.
  • The clear consensus among human rights experts and several high-ranking intelligence experts, including the former directors of the NSA, Office of the Director of National Intelligence, and DHS, is that mandating encryption backdoors is dangerous. Unaddressed Concerns: Preventing Encrypted Devices from Entering the US and the Slippery Slope In addition to the significant faults in Vance’s arguments in favor of his proposal, he fails to address the question of how such a restriction would be effectively implemented. There is no effective mechanism for preventing code from becoming available for download online, even if it is illegal. One critical issue the Vance proposal fails to address is how the government would prevent, or even identify, encrypted smartphones when individuals bring them into the United States. DHS would have to train customs agents to search the contents of every person’s phone in order to identify whether it is encrypted, and then confiscate the phones that are. Legal and policy considerations aside, this kind of policy is, at the very least, impractical. Preventing strong encryption from entering the US is not like preventing guns or drugs from entering the country — encrypted phones aren’t immediately obvious as is contraband. Millions of people use encrypted devices, and tens of millions more devices are shipped to and sold in the US each year.
  • Finally, there is a real concern that if Vance’s proposal were accepted, it would be the first step down a slippery slope. Right now, his proposal only calls for access to smartphones and devices running mobile operating systems. While this policy in and of itself would cover a number of commonplace devices, it may eventually be expanded to cover laptop and desktop computers, as well as communications in transit. The expansion of this kind of policy is even more worrisome when taking into account the speed at which technology evolves and becomes widely adopted. Ten years ago, the iPhone did not even exist. Who is to say what technology will be commonplace in 10 or 20 years that is not even around today. There is a very real question about how far law enforcement will go to gain access to information. Things that once seemed like merely science fiction, such as wearable technology and artificial intelligence that could be implanted in and work with the human nervous system, are now available. If and when there comes a time when our “smart phone” is not really a device at all, but is rather an implant, surely we would not grant law enforcement access to our minds.
  • Policymakers should dismiss Vance’s proposal to prohibit the use of strong encryption to protect our smartphones and devices in order to ensure law enforcement access. Undermining encryption, regardless of whether it is protecting data in transit or at rest, would take us down a dangerous and harmful path. Instead, law enforcement and the intelligence community should be working to alter their skills and tactics in a fast-evolving technological world so that they are not so dependent on information that will increasingly be protected by encryption.

  • NSA Director Finally Admits Encryption Is Needed to Protect Public’s Privacy The new stance denotes a growing awareness within the government that Americans are not comfortable with the State’s grip on their data. By Carey Wedler | AntiMedia | January 22, 2016 Share this article! https://mail.google.com/mail/?view=cm&fs=1&to&su=NSA%20Director%20Finally%20Admits%20Encryption%20Is%20Needed%20to%20Protect%20Public%E2%80%99s%20Privacy&body=http%3A%2F%2Fwww.mintpress
  • Rogers cited the recent Office of Personnel Management hack of over 20 million users as a reason to increase encryption rather than scale it back. “What you saw at OPM, you’re going to see a whole lot more of,” he said, referring to the massive hack that compromised the personal data about 20 million people who obtained background checks. Rogers’ comments, while forward-thinking, signify an about face in his stance on encryption. In February 2015, he said he “shares [FBI] Director [James] Comey’s concern” about cell phone companies’ decision to add encryption features to their products. Comey has been one loudest critics of encryption. However, Rogers’ comments on Thursday now directly conflict with Comey’s stated position. The FBI director has publicly chastised encryption, as well as the companies that provide it. In 2014, he claimed Apple’s then-new encryption feature could lead the world to “a very dark place.” At a Department of Justice hearing in November, Comey testified that “Increasingly, the shadow that is ‘going dark’ is falling across more and more of our work.” Though he claimed, “We support encryption,” he insisted “we have a problem that encryption is crashing into public safety and we have to figure out, as people who care about both, to resolve it. So, I think the conversation’s in a healthier place.”
  • At the same hearing, Comey and Attorney General Loretta Lynch declined to comment on whether they had proof the Paris attackers used encryption. Even so, Comey recently lobbied for tech companies to do away with end-to-end encryption. However, his crusade has fallen on unsympathetic ears, both from the private companies he seeks to control — and from the NSA. Prior to Rogers’ statements in support of encryption Thursday, former NSA chief Michael Hayden said, “I disagree with Jim Comey. I actually think end-to-end encryption is good for America.” Still another former NSA chair has criticized calls for backdoor access to information. In October, Mike McConnell told a panel at an encryption summit that the United States is “better served by stronger encryption, rather than baking in weaker encryption.” Former Department of Homeland Security chief, Michael Chertoff, has also spoken out against government being able to bypass encryption.

  • Regardless of these individual defenses of encryption, the Intercept explained why these statements may be irrelevant: “Left unsaid is the fact that the FBI and NSA have the ability to circumvent encryption and get to the content too — by hacking. Hacking allows law enforcement to plant malicious code on someone’s computer in order to gain access to the photos, messages, and text before they were ever encrypted in the first place, and after they’ve been decrypted. The NSA has an entire team of advanced hackers, possibly as many as 600, camped out at Fort Meade.”
  • Rogers statements, of course, are not a full-fledged endorsement of privacy, nor can the NSA be expected to make it a priority. Even so, his new stance denotes a growing awareness within the government that Americans are not comfortable with the State’s grip on their data. “So spending time arguing about ‘hey, encryption is bad and we ought to do away with it’ … that’s a waste of time to me,” Rogers said Thursday. “So what we’ve got to ask ourselves is, with that foundation, what’s the best way for us to deal with it? And how do we meet those very legitimate concerns from multiple perspectives?”

The Latest Rules on How Long NSA Can Keep Americans' Encrypted Data Look Too Familiar |... - 0 views

surveillance state NSA IAA-2015 Sect-309 legislation

shared by Paul Merrell on 26 Jan 15 - No Cached
  • Does the National Security Agency (NSA) have the authority to collect and keep all encrypted Internet traffic for as long as is necessary to decrypt that traffic? That was a question first raised in June 2013, after the minimization procedures governing telephone and Internet records collected under Section 702 of the Foreign Intelligence Surveillance Act were disclosed by Edward Snowden. The issue quickly receded into the background, however, as the world struggled to keep up with the deluge of surveillance disclosures. The Intelligence Authorization Act of 2015, which passed Congress this last December, should bring the question back to the fore. It established retention guidelines for communications collected under Executive Order 12333 and included an exception that allows NSA to keep ‘incidentally’ collected encrypted communications for an indefinite period of time. This creates a massive loophole in the guidelines. NSA’s retention of encrypted communications deserves further consideration today, now that these retention guidelines have been written into law. It has become increasingly clear over the last year that surveillance reform will be driven by technological change—specifically by the growing use of encryption technologies. Therefore, any legislation touching on encryption should receive close scrutiny.
  • Section 309 of the intel authorization bill describes “procedures for the retention of incidentally acquired communications.” It establishes retention guidelines for surveillance programs that are “reasonably anticipated to result in the acquisition of [telephone or electronic communications] to or from a United States person.” Communications to or from a United States person are ‘incidentally’ collected because the U.S. person is not the actual target of the collection. Section 309 states that these incidentally collected communications must be deleted after five years unless they meet a number of exceptions. One of these exceptions is that “the communication is enciphered or reasonably believed to have a secret meaning.” This exception appears to be directly lifted from NSA’s minimization procedures for data collected under Section 702 of FISA, which were declassified in 2013. 
  • While Section 309 specifically applies to collection taking place under E.O. 12333, not FISA, several of the exceptions described in Section 309 closely match exceptions in the FISA minimization procedures. That includes the exception for “enciphered” communications. Those minimization procedures almost certainly served as a model for these retention guidelines and will likely shape how this new language is interpreted by the Executive Branch. Section 309 also asks the heads of each relevant member of the intelligence community to develop procedures to ensure compliance with new retention requirements. I expect those procedures to look a lot like the FISA minimization guidelines.
  • ...6 more annotations...
  • This language is broad, circular, and technically incoherent, so it takes some effort to parse appropriately. When the minimization procedures were disclosed in 2013, this language was interpreted by outside commentators to mean that NSA may keep all encrypted data that has been incidentally collected under Section 702 for at least as long as is necessary to decrypt that data. Is this the correct interpretation? I think so. It is important to realize that the language above isn’t just broad. It seems purposefully broad. The part regarding relevance seems to mirror the rationale NSA has used to justify its bulk phone records collection program. Under that program, all phone records were relevant because some of those records could be valuable to terrorism investigations and (allegedly) it isn’t possible to collect only those valuable records. This is the “to find a needle a haystack, you first have to have the haystack” argument. The same argument could be applied to encrypted data and might be at play here.
  • This exception doesn’t just apply to encrypted data that might be relevant to a current foreign intelligence investigation. It also applies to cases in which the encrypted data is likely to become relevant to a future intelligence requirement. This is some remarkably generous language. It seems one could justify keeping any type of encrypted data under this exception. Upon close reading, it is difficult to avoid the conclusion that these procedures were written carefully to allow NSA to collect and keep a broad category of encrypted data under the rationale that this data might contain the communications of NSA targets and that it might be decrypted in the future. If NSA isn’t doing this today, then whoever wrote these minimization procedures wanted to at least ensure that NSA has the authority to do this tomorrow.
  • There are a few additional observations that are worth making regarding these nominally new retention guidelines and Section 702 collection. First, the concept of incidental collection as it has typically been used makes very little sense when applied to encrypted data. The way that NSA’s Section 702 upstream “about” collection is understood to work is that technology installed on the network does some sort of pattern match on Internet traffic; say that an NSA target uses example@gmail.com to communicate. NSA would then search content of emails for references to example@gmail.com. This could notionally result in a lot of incidental collection of U.S. persons’ communications whenever the email that references example@gmail.com is somehow mixed together with emails that have nothing to do with the target. This type of incidental collection isn’t possible when the data is encrypted because it won’t be possible to search and find example@gmail.com in the body of an email. Instead, example@gmail.com will have been turned into some alternative, indecipherable string of bits on the network. Incidental collection shouldn’t occur because the pattern match can’t occur in the first place. This demonstrates that, when communications are encrypted, it will be much harder for NSA to search Internet traffic for a unique ID associated with a specific target.
  • This lends further credence to the conclusion above: rather than doing targeted collection against specific individuals, NSA is collecting, or plans to collect, a broad class of data that is encrypted. For example, NSA might collect all PGP encrypted emails or all Tor traffic. In those cases, NSA could search Internet traffic for patterns associated with specific types of communications, rather than specific individuals’ communications. This would technically meet the definition of incidental collection because such activity would result in the collection of communications of U.S. persons who aren’t the actual targets of surveillance. Collection of all Tor traffic would entail a lot of this “incidental” collection because the communications of NSA targets would be mixed with the communications of a large number of non-target U.S. persons. However, this “incidental” collection is inconsistent with how the term is typically used, which is to refer to over-collection resulting from targeted surveillance programs. If NSA were collecting all Tor traffic, that activity wouldn’t actually be targeted, and so any resulting over-collection wouldn’t actually be incidental. Moreover, greater use of encryption by the general public would result in an ever-growing amount of this type of incidental collection.
  • This type of collection would also be inconsistent with representations of Section 702 upstream collection that have been made to the public and to Congress. Intelligence officials have repeatedly suggested that search terms used as part of this program have a high degree of specificity. They have also argued that the program is an example of targeted rather than bulk collection. ODNI General Counsel Robert Litt, in a March 2014 meeting before the Privacy and Civil Liberties Oversight Board, stated that “there is either a misconception or a mischaracterization commonly repeated that Section 702 is a form of bulk collection. It is not bulk collection. It is targeted collection based on selectors such as telephone numbers or email addresses where there’s reason to believe that the selector is relevant to a foreign intelligence purpose.” The collection of Internet traffic based on patterns associated with types of communications would be bulk collection; more akin to NSA’s collection of phone records en mass than it is to targeted collection focused on specific individuals. Moreover, this type of collection would certainly fall within the definition of bulk collection provided just last week by the National Academy of Sciences: “collection in which a significant portion of the retained data pertains to identifiers that are not targets at the time of collection.”
  • The Section 702 minimization procedures, which will serve as a template for any new retention guidelines established for E.O. 12333 collection, create a large loophole for encrypted communications. With everything from email to Internet browsing to real-time communications moving to encrypted formats, an ever-growing amount of Internet traffic will fall within this loophole.
  • Paul Merrell on 26 Jan 15
     
    Tucked into a budget authorization act in December without press notice. Section 309 (the Act is linked from the article) appears to be very broad authority for the NSA to intercept any form of telephone or other electronic information in bulk. There are far more exceptions from the five-year retention limitation than the encrypted information exception. When reading this, keep in mind that the U.S. intelligence community plays semantic games to obfuscate what it does. One of its word plays is that communications are not "collected" until an analyst looks at or listens to partiuclar data, even though the data will be searched to find information countless times before it becomes "collected." That searching was the major basis for a decision by the U.S. District Court in Washington, D.C. that bulk collection of telephone communications was unconstitutional: Under the Fourth Amendment, a "search" or "seizure" requiring a judicial warrant occurs no later than when the information is intercepted. That case is on appeal, has been briefed and argued, and a decision could come any time now. Similar cases are pending in two other courts of appeals. Also, an important definition from the new Intelligence Authorization Act: "(a) DEFINITIONS.-In this section: (1) COVERED COMMUNICATION.-The term ''covered communication'' means any nonpublic telephone or electronic communication acquired without the consent of a person who is a party to the communication, including communications in electronic storage."

surveillance state FBI Comey encryption backdoors

shared by Paul Merrell on 21 May 15 - No Cached
  • Earlier today, FBI Director James Comey implied that a broad coalition of technology companies, trade associations, civil society groups, and security experts were either uninformed or were not “fair-minded” in a letter they sent to the President yesterday urging him to reject any legislative proposals that would undermine the adoption of strong encryption by US companies. The letter was signed by dozens of organizations and companies in the latest part of the debate over whether the government should be given built-in access to encrypted data (see, for example, here, here, here, and here for previous iterations). The comments were made at the Third Annual Cybersecurity Law Institute held at Georgetown University Law Center. The transcript of his encryption-related discussion is below (emphasis added).
  • Increasingly, communications at rest sitting on a device or in motion are encrypted. The device is encrypted or the communication is encrypted and therefore unavailable to us even with a court order. So I make a showing of probable cause to a judge in a criminal case or in an intelligence case to the Foreign Intelligence Surveillance Court judge that the content of a particular defense or a particular communication stream should be collected to our statutory authority, and the judge approves, increasingly we are finding ourselves unable to read what we find or we’re unable to open a device. And that is a serious concern. I am actually — I think encryption is a good thing. I think there are tremendous societal benefits to encryption. That’s one of the reasons the FBI tells people not only lock your cars, but you should encrypt things that are important to you to make it harder for thieves to take them.
  • But we have a collision going on in this country that’s getting closer and closer to an actual head-on, which is our important interest in privacy — which I am passionate about — and our important interest in public safety. The logic of universal encryption is inexorable that our authority under the Fourth Amendment — an amendment that I think is critical to ordered liberty — with the right predication and the right oversight to obtain information is going to become increasingly irrelevant. As all of our lives become digital, the logic of encryption is that all of our lives will be covered by strong encryption, therefore all of our lives — I know there are no criminals here, but including the lives of criminals and terrorists and spies — will be in a place that is utterly unavailable to court ordered process. And that, I think, to a democracy should be very, very concerning. I think we need to have a conversation about it. Again, how do we strike the right balance? Privacy matters tremendously. Public safety, I think, matters tremendously to everybody. I think fair-minded people have to recognize that there are tremendous benefits to a society from encryption. There are tremendous costs to a society from universal strong encryption. And how do we think about that?
  • ...2 more annotations...
  • A group of tech companies and some prominent folks wrote a letter to the President yesterday that I frankly found depressing. Because their letter contains no acknowledgment that there are societal costs to universal encryption. Look, I recognize the challenges facing our tech companies. Competitive challenges, regulatory challenges overseas, all kinds of challenges. I recognize the benefits of encryption, but I think fair-minded people also have to recognize the costs associated with that. And I read this letter and I think, “Either these folks don’t see what I see or they’re not fair-minded.” And either one of those things is depressing to me. So I’ve just got to continue to have the conversation. I don’t know the answer, but I don’t think a democracy should drift to a place where suddenly law enforcement people say, “Well, actually we — the Fourth Amendment is an awesome thing, but we actually can’t access any information.”
  • We’ve got to have a conversation long before the logic of strong encryption takes us to that place. And smart people, reasonable people will disagree mightily. Technical people will say it’s too hard. My reaction to that is: Really? Too hard? Too hard for the people we have in this country to figure something out? I’m not that pessimistic. I think we ought to have a conversation.
  • Paul Merrell on 21 May 15
     
    Considering that I'm over 10 times as likely to die from a police shoooting as I am from a terrorist attack, how about we begin this conversation, Mr. Comey, by you providing formal notice to everyone who's had the telephone metadata gathered or searched all dates on which such gatherings and searches were conducted so citizens can file suit for violation of their privacy rights? Note that the Second U.S. Circuit Court of Appeals held last week that the FBI exceeded statutory authority in gathering and searching that information. Because the gathering and searching was not authorized, that would bring the gathering and searching under the protections of the Privacy Act, including the FBI duty to account for the disclosures  and to pay at least the statutory minimum $1,500 in damges per incident.  Then I would like to have an itemization of all of the commercial software and hardware products that your agency and or your buddies at NSA built backdoors into.  Then your resignation for millions of violations of the Privacy Act would be deeply appreciated. Please feel free to delegate the above mentioned tasks to your successor.

  • The National Security Agency is winning its long-running secret war on encryption, using supercomputers, technical trickery, court orders and behind-the-scenes persuasion to undermine the major tools protecting the privacy of everyday communications in the Internet age, according to newly disclosed documents.
  • The agency has circumvented or cracked much of the encryption, or digital scrambling, that guards global commerce and banking systems, protects sensitive data like trade secrets and medical records, and automatically secures the e-mails, Web searches, Internet chats and phone calls of Americans and others around the world, the documents show.
  • The N.S.A. hacked into target computers to snare messages before they were encrypted. In some cases, companies say they were coerced by the government into handing over their master encryption keys or building in a back door. And the agency used its influence as the world’s most experienced code maker to covertly introduce weaknesses into the encryption standards followed by hardware and software developers around the world.

  • “For the past decade, N.S.A. has led an aggressive, multipronged effort to break widely used Internet encryption technologies,” said a 2010 memo describing a briefing about N.S.A. accomplishments for employees of its British counterpart, Government Communications Headquarters, or GCHQ. “Cryptanalytic capabilities are now coming online. Vast amounts of encrypted Internet data which have up till now been discarded are now exploitable.”
  • Some of the agency’s most intensive efforts have focused on the encryption in universal use in the United States, including Secure Sockets Layer, or SSL; virtual private networks, or VPNs; and the protection used on fourth-generation, or 4G, smartphones. Many Americans, often without realizing it, rely on such protection every time they send an e-mail, buy something online, consult with colleagues via their company’s computer network, or use a phone or a tablet on a 4G network.
  • For at least three years, one document says, GCHQ, almost certainly in collaboration with the N.S.A., has been looking for ways into protected traffic of popular Internet companies: Google, Yahoo, Facebook and Microsoft’s Hotmail. By 2012, GCHQ had developed “new access opportunities” into Google’s systems, according to the document. (Google denied giving any government access and said it had no evidence its systems had been breached).
  • Paul Kocher, a leading cryptographer who helped design the SSL protocol, recalled how the N.S.A. lost the heated national debate in the 1990s about inserting into all encryption a government back door called the Clipper Chip. “And they went and did it anyway, without telling anyone,” Mr. Kocher said. He said he understood the agency’s mission but was concerned about the danger of allowing it unbridled access to private information.
  • The documents are among more than 50,000 shared by The Guardian with The New York Times and ProPublica, the nonprofit news organization. They focus on GCHQ but include thousands from or about the N.S.A. Intelligence officials asked The Times and ProPublica not to publish this article, saying it might prompt foreign targets to switch to new forms of encryption or communications that would be harder to collect or read. The news organizations removed some specific facts but decided to publish the article because of the value of a public debate about government actions that weaken the most powerful privacy tools.
  • The files show that the agency is still stymied by some encryption, as Mr. Snowden suggested in a question-and-answer session on The Guardian’s Web site in June. “Properly implemented strong crypto systems are one of the few things that you can rely on,” he said, though cautioning that the N.S.A. often bypasses the encryption altogether by targeting the computers at one end or the other and grabbing text before it is encrypted or after it is decrypted.
  • Because strong encryption can be so effective, classified N.S.A. documents make clear, the agency’s success depends on working with Internet companies — by getting their voluntary collaboration, forcing their cooperation with court orders or surreptitiously stealing their encryption keys or altering their software or hardware.
  • At Microsoft, as The Guardian has reported, the N.S.A. worked with company officials to get pre-encryption access to Microsoft’s most popular services, including Outlook e-mail, Skype Internet phone calls and chats, and SkyDrive, the company’s cloud storage service.
  • Simultaneously, the N.S.A. has been deliberately weakening the international encryption standards adopted by developers. One goal in the agency’s 2013 budget request was to “influence policies, standards and specifications for commercial public key technologies,” the most common encryption method. Cryptographers have long suspected that the agency planted vulnerabilities in a standard adopted in 2006 by the National Institute of Standards and Technology and later by the International Organization for Standardization, which has 163 countries as members. Classified N.S.A. memos appear to confirm that the fatal weakness, discovered by two Microsoft cryptographers in 2007, was engineered by the agency. The N.S.A. wrote the standard and aggressively pushed it on the international group, privately calling the effort “a challenge in finesse.” “Eventually, N.S.A. became the sole editor,” the memo says.
  • But the agencies’ goal was to move away from decrypting targets’ tools one by one and instead decode, in real time, all of the information flying over the world’s fiber optic cables and through its Internet hubs, only afterward searching the decrypted material for valuable intelligence. A 2010 document calls for “a new approach for opportunistic decryption, rather than targeted.” By that year, a Bullrun briefing document claims that the agency had developed “groundbreaking capabilities” against encrypted Web chats and phone calls. Its successes against Secure Sockets Layer and virtual private networks were gaining momentum.
  • Ladar Levison, the founder of Lavabit, wrote a public letter to his disappointed customers, offering an ominous warning. “Without Congressional action or a strong judicial precedent,” he wrote, “I would strongly recommend against anyone trusting their private data to a company with physical ties to the United States.”

Operation AURORAGOLD: How the NSA Hacks Cellphone Networks Worldwide - 0 views

surveillance state NSA NSA-methods cell-network-penetration AURORAGOLD

shared by Paul Merrell on 06 Dec 14 - No Cached
  • In March 2011, two weeks before the Western intervention in Libya, a secret message was delivered to the National Security Agency. An intelligence unit within the U.S. military’s Africa Command needed help to hack into Libya’s cellphone networks and monitor text messages. For the NSA, the task was easy. The agency had already obtained technical information about the cellphone carriers’ internal systems by spying on documents sent among company employees, and these details would provide the perfect blueprint to help the military break into the networks. The NSA’s assistance in the Libya operation, however, was not an isolated case. It was part of a much larger surveillance program—global in its scope and ramifications—targeted not just at hostile countries.
  • According to documents contained in the archive of material provided to The Intercept by whistleblower Edward Snowden, the NSA has spied on hundreds of companies and organizations internationally, including in countries closely allied to the United States, in an effort to find security weaknesses in cellphone technology that it can exploit for surveillance. The documents also reveal how the NSA plans to secretly introduce new flaws into communication systems so that they can be tapped into—a controversial tactic that security experts say could be exposing the general population to criminal hackers. Codenamed AURORAGOLD, the covert operation has monitored the content of messages sent and received by more than 1,200 email accounts associated with major cellphone network operators, intercepting confidential company planning papers that help the NSA hack into phone networks.
  • Karsten Nohl, a leading cellphone security expert and cryptographer who was consulted by The Intercept about details contained in the AURORAGOLD documents, said that the broad scope of information swept up in the operation appears aimed at ensuring virtually every cellphone network in the world is NSA accessible.
  • ...11 more annotations...
  • “Collecting an inventory [like this] on world networks has big ramifications,” Nohl said, because it allows the NSA to track and circumvent upgrades in encryption technology used by cellphone companies to shield calls and texts from eavesdropping. Evidence that the agency has deliberately plotted to weaken the security of communication infrastructure, he added, was particularly alarming. “Even if you love the NSA and you say you have nothing to hide, you should be against a policy that introduces security vulnerabilities,” Nohl said, “because once NSA introduces a weakness, a vulnerability, it’s not only the NSA that can exploit it.”
  • The AURORAGOLD operation is carried out by specialist NSA surveillance units whose existence has not been publicly disclosed: the Wireless Portfolio Management Office, which defines and carries out the NSA’s strategy for exploiting wireless communications, and the Target Technology Trends Center, which monitors the development of new communication technology to ensure that the NSA isn’t blindsided by innovations that could evade its surveillance reach. The center’s logo is a picture of the Earth overshadowed by a large telescope; its motto is “Predict – Plan – Prevent.”
  • The NSA documents reveal that, as of May 2012, the agency had collected technical information on about 70 percent of cellphone networks worldwide—701 of an estimated 985—and was maintaining a list of 1,201 email “selectors” used to intercept internal company details from employees. (“Selector” is an agency term for a unique identifier like an email address or phone number.) From November 2011 to April 2012, between 363 and 1,354 selectors were “tasked” by the NSA for surveillance each month as part of AURORAGOLD, according to the documents. The secret operation appears to have been active since at least 2010.
  • By covertly monitoring GSMA working groups in a bid to identify and exploit security vulnerabilities, the NSA has placed itself into direct conflict with the mission of the National Institute for Standards and Technology, or NIST, the U.S. government agency responsible for recommending cybersecurity standards in the United States. NIST recently handed out a grant of more than $800,000 to GSMA so that the organization could research ways to address “security and privacy challenges” faced by users of mobile devices. The revelation that the trade group has been targeted for surveillance may reignite deep-seated tensions between NIST and NSA that came to the fore following earlier Snowden disclosures. Last year, NIST was forced to urge people not to use an encryption standard it had previously approved after it emerged NSA had apparently covertly worked to deliberately weaken it.
  • The NSA focuses on intercepting obscure but important technical documents circulated among the GSMA’s members known as “IR.21s.” Most cellphone network operators share IR.21 documents among each other as part of agreements that allow their customers to connect to foreign networks when they are “roaming” overseas on a vacation or a business trip. An IR.21, according to the NSA documents, contains information “necessary for targeting and exploitation.” The details in the IR.21s serve as a “warning mechanism” that flag new technology used by network operators, the NSA’s documents state. This allows the agency to identify security vulnerabilities in the latest communication systems that can be exploited, and helps efforts to introduce new vulnerabilities “where they do not yet exist.” The IR.21s also contain details about the encryption used by cellphone companies to protect the privacy of their customers’ communications as they are transmitted across networks. These details are highly sought after by the NSA, as they can aid its efforts to crack the encryption and eavesdrop on conversations.
  • One of the prime targets monitored under the AURORAGOLD program is the London-headquartered trade group, the GSM Association, or the GSMA, which represents the interests of more than 800 major cellphone, software, and internet companies from 220 countries. The GSMA’s members include U.S.-based companies such as Verizon, AT&T, Sprint, Microsoft, Facebook, Intel, Cisco, and Oracle, as well as large international firms including Sony, Nokia, Samsung, Ericsson, and Vodafone. The trade organization brings together its members for regular meetings at which new technologies and policies are discussed among various “working groups.” The Snowden files reveal that the NSA specifically targeted the GSMA’s working groups for surveillance.
  • Last year, the Washington Post reported that the NSA had already managed to break the most commonly used cellphone encryption algorithm in the world, known as A5/1. But the information collected under AURORAGOLD allows the agency to focus on circumventing newer and stronger versions of A5 cellphone encryption, such as A5/3. The documents note that the agency intercepts information from cellphone operators about “the type of A5 cipher algorithm version” they use, and monitors the development of new algorithms in order to find ways to bypass the encryption. In 2009, the British surveillance agency Government Communications Headquarters conducted a similar effort to subvert phone encryption under a project called OPULENT PUP, using powerful computers to perform a “crypt attack” to penetrate the A5/3 algorithm, secret memos reveal. By 2011, GCHQ was collaborating with the NSA on another operation, called WOLFRAMITE, to attack A5/3 encryption. (GCHQ declined to comment for this story, other than to say that it operates within legal parameters.)
  • The extensive attempts to attack cellphone encryption have been replicated across the Five Eyes surveillance alliance. Australia’s top spy agency, for instance, infiltrated an Indonesian cellphone company and stole nearly 1.8 million encryption keys used to protect communications, the New York Times reported in February.
  • The NSA’s documents show that it focuses on collecting details about virtually all technical standards used by cellphone operators, and the agency’s efforts to stay ahead of the technology curve occasionally yield significant results. In early 2010, for instance, its operatives had already found ways to penetrate a variant of the newest “fourth generation” smartphone-era technology for surveillance, years before it became widely adopted by millions of people in dozens of countries. The NSA says that its efforts are targeted at terrorists, weapons proliferators, and other foreign targets, not “ordinary people.” But the methods used by the agency and its partners to gain access to cellphone communications risk significant blowback. According to Mikko Hypponen, a security expert at Finland-based F-Secure, criminal hackers and foreign government adversaries could be among the inadvertent beneficiaries of any security vulnerabilities or encryption weaknesses inserted by the NSA into communication systems using data collected by the AURORAGOLD project.
  • Vines, the NSA spokeswoman, told The Intercept that the agency was committed to ensuring an “open, interoperable, and secure global internet.” “NSA deeply values these principles and takes great care to honor them in the performance of its lawful foreign-intelligence mission,” Vines said.

    I wound up joining this campaign at the urging of the ACLU after checking the Privacy Policy. The Reset the Net campaign seems to be endorsed by a lot of change-oriented groups, from the ACLU to Greenpeac to the Pirate Party. A fair number of groups with a Progressive agenda, but certainly not limited to them. The right answer to that situation is to urge other groups to endorse, not to avoid the campaign. Single-issue coalition-building is all about focusing on an area of agreement rather than worrying about who you are rubbing elbows with.  I have been looking for a a bipartisan group that's tackling government surveillance issues via mass actions but has no corporate sponsors. This might be the one. The reason: Corporate types like Google have no incentive to really butt heads with the government voyeurs. They are themselves engaged in massive surveillance of their users and certainly will not carry the battle for digital privacy over to the private sector. But this *is* a battle over digital privacy and legally defining user privacy rights in the private sector is just as important as cutting back on government surveillance. As we have learned through the Snowden disclosures, what the private internet companies have, the NSA can and does get.  The big internet services successfully pushed in the U.S. for authorization to publish more numbers about how many times they pass private data to the government, but went no farther. They wanted to be able to say they did something, but there's a revolving door of staffers between NSA and the big internet companies and the internet service companies' data is an open book to the NSA.   The big internet services are not champions of their users' privacy. If they were, they would be featuring end-to-end encryption with encryption keys unique to each user and unknown to the companies.  Like some startups in Europe are doing.

Verizon's New, Encrypted Calling App Plays Nice With the NSA - Businessweek - 0 views

surveillance state Verizon backdoors pseudo-encryption

shared by Paul Merrell on 13 Dec 14 - No Cached
  • Verizon is the latest big company to enter the post-Snowden market for secure communication, and it's doing so with an encryption standard that comes with a way for law enforcement to access ostensibly secure phone conversations.Verizon Voice Cypher, the product introduced on Thursday with the encryption company Cellcrypt, offers business and government customers end-to-end encryption for voice calls on iOS, Android, or BlackBerry devices equipped with a special app. The encryption software provides secure communications for people speaking on devices with the app, regardless of their wireless carrier, and it can also connect to an organization's secure phone system. Cellcrypt and Verizon both say that law enforcement agencies will be able to access communications that take place over Voice Cypher, so long as they're able to prove that there's a legitimate law enforcement reason for doing so. Seth Polansky, Cellcrypt's vice president for North America, disputes the idea that building technology to allow wiretapping is a security risk. "It's only creating a weakness for government agencies," he says. "Just because a government access option exists, it doesn't mean other companies can access it." 
  • Phone carriers like Verizon are required by U.S. law to build networks that can be wiretapped. But the legislation known as the Communications Assistance for Law Enforcement Act requires phone carriers to decrypt communications for the government only if they have designed their technology to make it possible to do so. If Verizon and Cellcrypt had structured their encryption so that neither company had the information necessary to decrypt the calls, they would not have been breaking the law.
  • Other companies have designed their encryption in this way, including AT&T, which offers encrypted phone service for business customers. Apple and Android recently began protecting content stored on users's phones in a way that would keep the tech companies from being able to comply with requests from law enforcement. The move drew public criticism from FBI Director James Comey, and some security experts expect that a renewed effort to stir passage of legislation banning such encryption will accompany Silicon Valley's increased interest in developing these services. Verizon believes major demand for its new encryption service will come from governmental agencies conveying sensitive but unclassified information over the phone, says Tim Petsky, a senior product manager for Verizon Wireless. Corporate customers who are concerned about corporate espionage are also itching for answers. "You read about breaches in security almost every week in the press," says Petsky. "Enterprise customers have been asking about ways to secure their communications and up until this point, we didn't have a solution."

  • There has been increased interest in encryption from individual consumers, too, largely thanks to the NSA revelations leaked by Edward Snowden. Yahoo and Google began offering end-to-end encrypted e-mail services this year. Silent Circle, a startup catering to consumer and enterprise clients, has been developing end-to-end voice encryption for phones calls. Verizon's service, with a monthly price of $45 per device, isn't targeting individual buyers and won't be offered to average consumers in the near future.But Verizon's partner, Cellcrypt, looks upon selling to large organizations as the first step toward bringing down the price before eventually offering a consumer-level encryption service. "At the end of the day, we'd love to have this be a line item on your Verizon bill," says Polansky.
  • Many people in the security industry believe that a designed access point creates a vulnerability for criminals or spies to exploit. Last year reports surfaced that the FBI was pushing legislation that would require many forms of Internet communication to be wiretap-ready. A group of prominent security experts responded strongly: "Requiring software vendors to build intercept functionality into their products is unwise and will be ineffective, with the result being serious consequences (PDF) for the economic well-being and national security of the United States," they wrote in a report issued in May.

You Should Really Consider Installing Signal, an Encrypted Messaging App for iPhone - T... - 0 views

surveillance state encryption iPhone Android Open-Whisper

shared by Paul Merrell on 06 Mar 15 - No Cached
  • In the age of ubiquitous government surveillance, the only way citizens can protect their privacy online is through encryption. Historically, this has been extremely difficult for mere mortals; just watch the video Edward Snowden made to teach Glenn Greenwald how to encrypt his emails to see how confusing it gets. But all of this is quickly changing as high-quality, user-friendly encryption software becomes available. App maker Open Whisper Systems took an important step in this direction today with the release of a major new version of its Signal encrypted calling app for iPhones and iPads. The new version, Signal 2.0, folds in support for encrypted text messages using a protocol called TextSecure, meaning users can communicate using voice and text while remaining confident nothing can be intercepted in transit over the internet. That may not sound like a particularly big deal, given that other encrypted communication apps are available for iOS, but Signal 2.0 offers something tremendously useful: peace of mind. Unlike other text messaging products, Signal’s code is open source, meaning it can be inspected by experts, and the app also supports forward secrecy, so if an attacker steals your encryption key, they cannot go back and decrypt messages they may have collected in the past.
  • Signal is also one special place on the iPhone where users can be confident all their communications are always fully scrambled. Other apps with encryption tend to enter insecure modes at unpredictable times — unpredictable for many users, at least. Apple’s iMessage, for example, employs strong encryption, but only when communicating between two Apple devices and only when there is a proper data connection. Otherwise, iMessage falls back on insecure SMS messaging. iMessage also lacks forward secrecy and inspectable source code. Signal also offers the ability for power users to verify the identity of the people they’re talking to, confirming that the encryption isn’t under attack. With iMessage, you just have to take Apple’s word for it. Strong, reliable, predictably-applied encryption is especially important at a time when the world just found out, via a report by The Intercept, that American and British spies hacked into the world’s largest SIM card manufacturer and stole the encryption keys that are used to protect communication between handsets and cell phone towers. With these keys, spies can eavesdrop on phone calls and texts just by passively listening to the airwaves.
  • iPhone users can find Signal here. For Android users, the product is, at the moment, split into two apps: TextSecure for private texting and RedPhone for private voice calls. “We’re working towards a single unified Signal app for Android, iPhone and the desktop,” says Marlinspike. It’s important to keep in mind that no technology is 100 percent secure, and an encrypted messaging app can only be as secure as the device you install it on. Intelligence agencies and other hackers can still exploit security bugs that have not been fixed, known as zero day exploits, to take over smartphones and bypass the encryption that privacy apps employ. But apps like Signal go a long way to making mass surveillance of billions of innocent people infeasible.

surveillance-state NSA GCHQ encryption hypocrisy

shared by Paul Merrell on 17 Jan 15 - No Cached
  • A secret US cybersecurity report warned that government and private computers were being left vulnerable to online attacks from Russia, China and criminal gangs because encryption technologies were not being implemented fast enough. The advice, in a newly uncovered five-year forecast written in 2009, contrasts with the pledge made by David Cameron this week to crack down on encryption use by technology companies.
  • In the wake of the Paris terror attacks, the prime minister said there should be no “safe spaces for terrorists to communicate” or that British authorites could not access. Cameron, who landed in the US on Thursday night, is expected to urge Barack Obama to apply more pressure to tech giants, such as Apple, Google and Facebook, which have been expanding encrypted messaging for their millions of users since the revelations of mass NSA surveillance by the whistleblower Edward Snowden.
  • Cameron said the companies “need to work with us. They need also to demonstrate, which they do, that they have a social responsibility to fight the battle against terrorism. We shouldn’t allow safe spaces for terrorists to communicate. That’s a huge challenge but that’s certainly the right principle”. But the document from the US National Intelligence Council, which reports directly to the US director of national intelligence, made clear that encryption was the “best defence” for computer users to protect private data. Part of the cache given to the Guardian by Snowden was published in 2009 and gives a five-year forecast on the “global cyber threat to the US information infrastructure”. It covers communications, commercial and financial networks, and government and critical infrastructure systems. It was shared with GCHQ and made available to the agency’s staff through its intranet.
  • ...6 more annotations...
  • An unclassified table accompanying the report states that encryption is the “[b]est defense to protect data”, especially if made particularly strong through “multi-factor authentication” – similar to two-step verification used by Google and others for email – or biometrics. These measures remain all but impossible to crack, even for GCHQ and the NSA. The report warned: “Almost all current and potential adversaries – nations, criminal groups, terrorists, and individual hackers – now have the capability to exploit, and in some cases attack, unclassified access-controlled US and allied information systems.” It further noted that the “scale of detected compromises indicates organisations should assume that any controlled but unclassified networks of intelligence, operational or commercial value directly accessible from the internet are already potentially compromised by foreign adversaries”.
  • The report had some cause for optimism, especially in the light of Google and other US tech giants having in the months prior greatly increased their use of encryption efforts. “We assess with high confidence that security best practices applied to target networks would prevent the vast majority of intrusions,” it concluded. Official UK government security advice still recommends encryption among a range of other tools for effective network and information defence. However, end-to-end encryption – which means only the two people communicating with each other, and not the company carrying the message, can decode it – is problematic for intelligence agencies as it makes even warranted collection much more difficult.
  • The previous week, a day after the attack on the Charlie Hebdo office in Paris, the MI5 chief, Andrew Parker, called for new powers and warned that new technologies were making it harder to track extremists. In November, the head of GCHQ, Robert Hannigan, said US social media giants had become the “networks of choice” for terrorists. Chris Soghoian, principal senior policy analyst at the American Civil Liberties Union, said attempts by the British government to force US companies to weaken encryption faced many hurdles.
  • The Guardian, New York Times and ProPublica have previously reported the intelligence agencies’ broad efforts to undermine encryption and exploit rather than reveal vulnerabilities. This prompted Obama’s NSA review panel to warn that the agency’s conflicting missions caused problems, and so recommend that its cyber-security responsibilities be removed to prevent future issues.
  • The memo requested a renewal of the legal warrant allowing GCHQ to “modify” commercial software in violation of licensing agreements. The document cites examples of software the agency had hacked, including commonly used software to run web forums, and website administration tools. Such software are widely used by companies and individuals around the world. The document also said the agency had developed “capability against Cisco routers”, which would “allow us to re-route selected traffic across international links towards GCHQ’s passive collection systems”. GCHQ had also been working to “exploit” the anti-virus software Kaspersky, the document said. The report contained no information on the nature of the vulnerabilities found by the agency.
  • Michael Beckerman, president and CEO of the Internet Association, a lobby group that represents Facebook, Google, Reddit, Twitter, Yahoo and other tech companies, said: “Just as governments have a duty to protect to the public from threats, internet services have a duty to our users to ensure the security and privacy of their data. That’s why internet services have been increasing encryption security.”

  • This was a great year for adoption of HTTPS encryption for secure connections to websites. HTTPS is an essential technology for security and privacy on the Web, and we've long been asking sites to turn it on to protect their users from spying (and from censorship and tampering with site content). This year, lots of factors came together to make it happen, including ongoing news about surveillance, advances in Web server capacity, nudges from industry, government, and Web browsers, and the Let's Encrypt certificate authority. By some measures, more than half of page loads in Firefox and in Chrome are now secured with HTTPS—the first time this has ever happened in the Web's history. That's right: for the first time ever, most pages viewed on the Web were encrypted! (As another year-in-review post will discuss, browsers are also experimenting with and rolling out stronger encryption technologies to better protect those connections.)
  • Sites large and small took turned on HTTPS in 2016, often using certificates from the Let's Encrypt certificate authority (sometimes with EFF's Certbot software, or a range of other options). In just a single year of broad public availability, Let's Encrypt has now helped enable secure connections for over 21 million websites, most of which never had certificates before.
  • A sizeable part of the growth in HTTPS came from very large hosting providers that decided to make HTTPS a default for sites that they host, including OVH, Wordpress.com, Shopify, Tumblr, Squarespace, and many others. Sites they host, and visitors to those sites, can get a boost in security without having to do anything. (And we're getting ongoing benefits from providers like CloudFlare who made the switch in previous years.) A single hosting provider's decision can result in enabling encryption for hundreds of thousands or millions of customers; we hope others will take the plunge too! U.S. government sites also made significant progress adopting HTTPS this year, responding to the administration's guidance in support of HTTPS—a clear and practical explanation of why secure connections should be the default. A caveat: data from Google shows that use of HTTPS varies significantly from country to country, remaining especially uncommon in Japan. We've also heard that it's still uncommon across much of East and Southeast Asia. Next year, we'll have to find ways to bridge those gaps.

shared by Paul Merrell on 20 May 14 - No Cached
  • ne new email service promising "end-to-end" encryption launched on Friday, and others are being developed while major services such as Google Gmail and Yahoo Mail have stepped up security measures.A major catalyst for email encryption were revelations about widespread online surveillance in documents leaked by Edward Snowden, the former National Security Agency contractor."A lot of people were upset with those revelations, and that coalesced into this effort," said Jason Stockman, a co-developer of ProtonMail, a new encrypted email service which launched Friday with collaboration of scientists from Harvard, the Massachusetts Institute of Technology and the European research lab CERN.Stockman said ProtonMail aims to be as user-friendly as the major commercial services, but with extra security, and with its servers located in Switzerland to make it more difficult for US law enforcement to access.
  • "Our vision is to make encryption and privacy mainstream by making it easy to use," Stockman told AFP. "There's no installation. Everything happens behind the scenes automatically."Even though email encryption using special codes or keys, a system known as PGP, has been around for two decades, "it was so complicated," and did not gain widespread adoption, Stockman said.After testing over the past few months, ProtonMail went public Friday using a "freemium" model a basic account will be free with some added features for a paid account.
  • As our users from China, Iran, Russia, and other countries around the world have shown us in the past months, ProtonMail is an important tool for freedom of speech and we are happy to finally be able to provide this to the whole world," the company said in a blog post.Google and Yahoo recently announced efforts to encrypt their email communications, but some specialists say the effort falls short."These big companies don't want to encrypt your stuff because they spy on you, too," said Bruce Schneier, a well-known cryptographer and author who is chief technology officer for CO3 Systems."Hopefully, the NSA debate is creating incentives for people to build more encryption."Stockman said that with services like Gmail, even if data is encrypted, "they have the key right next to it if you have the key and lock next to each other, so it's pretty much useless."
  • ...3 more annotations...
  • By locating in Switzerland, ProtonMail hopes to avoid the legal woes of services like Lavabit widely believed to be used by Snowden which shut down rather than hand over data to the US government, and which now faces a contempt of court order.Even if a Swiss court ordered data to be turned over, Stockman said, "we would hand over piles of encrypted data. We don't have a key. We never see the password."
  • Lavabit founder Ladar Levison meanwhile hopes to launch a new service with other developers in a coalition known as the "Dark Mail Alliance."Levison told AFP he hopes to have a new encrypted email system in testing within a few months and widely available later this year."The goal is to make it ubiquitous, so people don't have to turn it on," he said.But he added that the technical hurdles are formidable, because the more user-friendly the system becomes, "the more susceptible it is to a sophisticated attacker with fake or spoofed key information."Levison said he hopes Dark Mail will become a new open standard that can be adopted by other email services.
  • on Callas, a cryptographer who developed the PGP standard and later co-founded the secure communications firm Silent Circle, cited challenges in making a system that is both secure and ubiquitous."If you are a bank you have to have an email system that complies with banking regulations," Callas told AFP, which could allow, for example, certain emails to be subject to regulatory or court review."Many of the services on the Internet started with zero security. We want to start with a system that is totally secure and let people dial it down."The new email system would complement Silent Circle's existing secure messaging system and encrypted mobile phone, which was launched earlier this year."If we start competing for customers on the basis of maximum privacy, that's good for everybody," Callas said.

  • Germany wants G20 leaders to agree to a concrete plan – one that includes affordable Internet access across the world by 2025, common technical standards and a focus on digital learning. Today, the G20 economies, like so many other economies around the world, are digital and interconnected. Digital services have opened up new avenues for sustainable economic growth. But, the digital economy will only continue to thrive and generate opportunities for citizens if the Internet is strong, secure, and trusted. Without this foundation, the global digital economy is at risk. Currently, there are 360 million people that take part in cross-border e-commerce. 28% of output in mature economies is digital. The Internet is set to contribute $6.6 trillion a year, or 7.1% of the total GDP in the G20 countries. And, by 2020, it’s estimated that more than 1 billion users will be added and there will be 30-50 billion additional connected devices. This level of interconnection will only boost the market. However, this cannot happen without a serious commitment by all parties to security and privacy. The truth is that economies can only function within a secure and trusted environment. Which brings us to encryption. Strong encryption is an essential piece to the future of the world’s economy and the Internet Society believes it should be the norm for all online transactions. It allows us to do our banking, conduct local and global business, run our power grids, operate, communications networks, and do almost everything else.
  • Encryption is a technical building block for securing infrastructure, communications and information. It should be made stronger and universal, not weaker. However, rather than being recognized as the way to secure our online transactions or our conversations, all too often the debate focuses on the use of encryption as a way to thwart law enforcement. To undermine the positive role of encryption in the name of security could have devastating consequences. Many great minds have already devoted considerable effort to resolving the conundrum posed by competing public policy objectives: providing security, safety and trust on the one hand, and law enforcement and legitimate policy goals on the other. But, it is time to stop kicking the encryption football up and down the field. Instead, we should recognize that encryption is key to the future digital economy and stop treating it as simply an obstacle to law enforcement. We need to deconstruct the issues faced by law enforcement and policy makers and agree together how we can achieve a trusted digital economy underpinned by encryption. This is the first time the G20 countries are holding a Ministerial on digital matters. It is also the first time that the G20 is inviting non-government stakeholders to contribute to these issues. This is a turning point that should not be missed. All views, including the technical perspective, must be at the table if we are to achieve progress on the G20’s ICT goals. If the G20 countries are serious about strengthening their economies and continuing to deliver economic and social prosperity to their citizens in future, there are three key principles they should endorse and implement immediately:
  • 1. Encryption is an important technical foundation for trust in the digital economy and should be the norm. All users (whether government, business or individual) should use encryption to protect infrastructure, communications and the privacy and integrity of their data. Encryption technologies should be strengthened, not weakened. 2. The security of the digital economy is a shared responsibility that needs the expertise and experience of all stakeholders, across border and across disciplines. It is an urgent need that will require open, inclusive collaboration. 3. Users’ rights should be at the heart of any decisions related to the digital economy. They are both the customers and the contributors to the success of the digital economy. The Internet Society calls for ubiquitous encryption for the Internet. We strongly believe that this is the best foundation for trust in the digital economy, and we urge the G20 nations to stand behind encryption.

surveillance state encryption FBI lies

  • In the last few months, several government officials, led by the FBI’s Director James Comey, have been complaining that the rise of encryption technologies would lead to a “very dark place” where cops and feds can’t fight and stop criminals. But new numbers released by the US government seem to contradict this doomsday scenario. In 2014, encryption thwarted four wiretaps out of 3,554, according to an annual report published on Wednesday by the US agency that oversees federal courts. The report reveals that state law enforcement agencies encountered encryption in 22 wiretaps last year. Out of those, cops were foiled on only two occasions. As for the feds, they encountered encryption in just three wiretaps, and could not decipher the intercepted communications in two of them.
  • In fact, cops found less encryption last year than in the year prior. In 2013, state authorities encountered encryption in 41 cases, versus 22 in 2014. At the federal level, there were three cases of encryption in 2014, against none in 2013. (The report also refers to five federal wiretaps conducted in “previous years” but only reported in 2014. Of those, the feds were able to crack the communications in four of the five.)
  • So far, the FBI has yet to put forth a valid example where encryption really thwarted an investigation. In fact, some of the examples cited by Comey have been debunked in media reports.

  • he Wiretap Report contains other interesting information that shed a light on government surveillance practices. Out of the more than 3,554 wiretaps authorized by judges, the vast majority of them (3,409 or 89 percent) were for drug related offenses. Homicide, in turn, was the reason behind only 4 percent of the the wiretaps. And virtually all of them (96%) were for “portable devices,” such as cellphones.Even if the Wiretap Report is just small a peek behind the scenes of government surveillance, it shows that for now, at least when it comes to wiretapping, the FBI’s isn’t really going dark.

Security Experts Oppose Government Access to Encrypted Communication - The New York Times - 0 views

encryption government-backdoors expert-report

shared by Paul Merrell on 08 Jul 15 - No Cached
  • An elite group of security technologists has concluded that the American and British governments cannot demand special access to encrypted communications without putting the world’s most confidential data and critical infrastructure in danger.A new paper from the group, made up of 14 of the world’s pre-eminent cryptographers and computer scientists, is a formidable salvo in a skirmish between intelligence and law enforcement leaders, and technologists and privacy advocates. After Edward J. Snowden’s revelations — with security breaches and awareness of nation-state surveillance at a record high and data moving online at breakneck speeds — encryption has emerged as a major issue in the debate over privacy rights.
  • That has put Silicon Valley at the center of a tug of war. Technology companies including Apple, Microsoft and Google have been moving to encrypt more of their corporate and customer data after learning that the National Security Agency and its counterparts were siphoning off digital communications and hacking into corporate data centers.
  • Yet law enforcement and intelligence agency leaders argue that such efforts thwart their ability to monitor kidnappers, terrorists and other adversaries. In Britain, Prime Minister David Cameron threatened to ban encrypted messages altogether. In the United States, Michael S. Rogers, the director of the N.S.A., proposed that technology companies be required to create a digital key to unlock encrypted data, but to divide the key into pieces and secure it so that no one person or government agency could use it alone.The encryption debate has left both sides bitterly divided and in fighting mode. The group of cryptographers deliberately issued its report a day before James B. Comey Jr., the director of the Federal Bureau of Investigation, and Sally Quillian Yates, the deputy attorney general at the Justice Department, are scheduled to testify before the Senate Judiciary Committee on the concerns that they and other government agencies have that encryption technologies will prevent them from effectively doing their jobs.

  • The new paper is the first in-depth technical analysis of government proposals by leading cryptographers and security thinkers, including Whitfield Diffie, a pioneer of public key cryptography, and Ronald L. Rivest, the “R” in the widely used RSA public cryptography algorithm. In the report, the group said any effort to give the government “exceptional access” to encrypted communications was technically unfeasible and would leave confidential data and critical infrastructure like banks and the power grid at risk. Handing governments a key to encrypted communications would also require an extraordinary degree of trust. With government agency breaches now the norm — most recently at the United States Office of Personnel Management, the State Department and the White House — the security specialists said authorities could not be trusted to keep such keys safe from hackers and criminals. They added that if the United States and Britain mandated backdoor keys to communications, China and other governments in foreign markets would be spurred to do the same.
  • “Such access will open doors through which criminals and malicious nation-states can attack the very individuals law enforcement seeks to defend,” the report said. “The costs would be substantial, the damage to innovation severe and the consequences to economic growth hard to predict. The costs to the developed countries’ soft power and to our moral authority would also be considerable.”

    Our system of government does not expect that every criminal will be apprehended and convicted. There are numerous values our society believes are more important. Some examples: [i] a presumption of innocence unless guilt is established beyond any reasonable doubt; [ii] the requirement that government officials convince a neutral magistrate that they have probable cause to believe that a search or seizure will produce evidence of a crime; [iii] many communications cannot be compelled to be disclosed and used in evidence, such as attorney-client communications, spousal communications, and priest-penitent communications; and [iv] etc. Moral of my story: the government needs a much stronger reason to justify interception of communications than saying, "some crooks will escape prosecution if we can't do that." We have a right to whisper to each other, concealing our communicatons from all others. Why does the right to whisper privately disappear if our whisperings are done electronically? The Supreme Court took its first step on a very slippery slope when it permitted wiretapping in Olmstead v. United States, 277 U.S. 438, 48 S. Ct. 564, 72 L. Ed. 944 (1928). https://goo.gl/LaZGHt It's been a long slide ever since. It's past time to revisit Olmstead and recognize that American citizens have the absolute right to communicate privately. "The President … recognizes that U.S. citizens and institutions should have a reasonable expectation of privacy from foreign or domestic intercept when using the public telephone system." - Brent Scowcroft, U.S. National Security Advisor, National Security Decision Memorandum 338 (1 September 1976) (Nixon administration), http://www.fas.org/irp/offdocs/nsdm-ford/nsdm-338.pdf

  • Today EFF is pleased to announce Let’s Encrypt, a new certificate authority (CA) initiative that we have put together with Mozilla, Cisco, Akamai, IdenTrust, and researchers at the University of Michigan that aims to clear the remaining roadblocks to transition the Web from HTTP to HTTPS.Although the HTTP protocol has been hugely successful, it is inherently insecure. Whenever you use an HTTP website, you are always vulnerable to problems, including account hijacking and identity theft; surveillance and tracking by governments, companies, and both in concert; injection of malicious scripts into pages; and censorship that targets specific keywords or specific pages on sites. The HTTPS protocol, though it is not yet flawless, is a vast improvement on all of these fronts, and we need to move to a future where every website is HTTPS by default.With a launch scheduled for summer 2015, the Let’s Encrypt CA will automatically issue and manage free certificates for any website that needs them. Switching a webserver from HTTP to HTTPS with this CA will be as easy as issuing one command, or clicking one button.
  • The biggest obstacle to HTTPS deployment has been the complexity, bureaucracy, and cost of the certificates that HTTPS requires. We’re all familiar with the warnings and error messages produced by misconfigured certificates. These warnings are a hint that HTTPS (and other uses of TLS/SSL) is dependent on a horrifyingly complex and often structurally dysfunctional bureaucracy for authentication.
  • The need to obtain, install, and manage certificates from that bureaucracy is the largest reason that sites keep using HTTP instead of HTTPS. In our tests, it typically takes a web developer 1-3 hours to enable encryption for the first time. The Let’s Encrypt project is aiming to fix that by reducing setup time to 20-30 seconds. You can help test and hack on the developer preview of our Let's Encrypt agent software or watch a video of it in action here:

  • Let’s Encrypt will employ a number of new technologies to manage secure automated verification of domains and issuance of certificates. We will use a protocol we’re developing called ACME between web servers and the CA, which includes support for new and stronger forms of domain validation. We will also employ Internet-wide datasets of certificates, such as EFF’s own Decentralized SSL Observatory, the University of Michigan’s scans.io, and Google's Certificate Transparency logs, to make higher-security decisions about when a certificate is safe to issue.The Let’s Encrypt CA will be operated by a new non-profit organization called the Internet Security Research Group (ISRG). EFF helped to put together this initiative with Mozilla and the University of Michigan, and it has been joined for launch by partners including Cisco, Akamai, and Identrust.

surveillance state encryption Apple Google Snowden Comey back-door-debate

  • As the Obama administration campaign to stop the commercialization of strong encryption heats up, National Security Agency whistleblower Edward Snowden is firing back on behalf of the companies like Apple and Google that are finding themselves under attack. “Technologists and companies working to protect ordinary citizens should be applauded, not sued or prosecuted,” Snowden wrote in an email through his lawyer. Snowden was asked by The Intercept to respond to the contentious suggestion — made Thursday on a blog that frequently promotes the interests of the national security establishment — that companies like Apple and Google might in certain cases be found legally liable for providing material aid to a terrorist organization because they provide encryption services to their users.
  • In his email, Snowden explained how law enforcement officials who are demanding that U.S. companies build some sort of window into unbreakable end-to-end encryption — he calls that an “insecurity mandate” — haven’t thought things through. “The central problem with insecurity mandates has never been addressed by its proponents: if one government can demand access to private communications, all governments can,” Snowden wrote. “No matter how good the reason, if the U.S. sets the precedent that Apple has to compromise the security of a customer in response to a piece of government paper, what can they do when the government is China and the customer is the Dalai Lama?”
  • Weakened encryption would only drive people away from the American technology industry, Snowden wrote. “Putting the most important driver of our economy in a position where they have to deal with the devil or lose access to international markets is public policy that makes us less competitive and less safe.”

  • FBI Director James Comey and others have repeatedly stated that law enforcement is “going dark” when it comes to the ability to track bad actors’ communications because of end-to-end encrypted messages, which can only be deciphered by the sender and the receiver. They have never provided evidence for that, however, and have put forth no technologically realistic alternative. Meanwhile, Apple and Google are currently rolling out user-friendly end-to-end encryption for their customers, many of whom have demanded greater privacy protections — especially following Snowden’s disclosures.

  • But while the interviewer focused on the Skype revelation, I thought the most interesting part was the other claim, “that the National Security Agency already had pre-encryption stage access to email on Outlook.”  Say what??  They can see the plaintext on my computer before I encrypt it? That defeats any/all encryption methods. How could they do that? Bypass Encryption While most outside observers think the NSA’s job is cracking encrypted messages, as the Prism disclosures have shown, the actual mission is simply to read all communications. Cracking codes is a last resort.
  • The NSA has a history of figuring out how to get to messages before or after they are encrypted. Whether it was by putting keyloggers on keyboards and recording the keystrokes or detecting the images of the characters as they were being drawn on a CRT. Today every desktop and laptop computer has another way for the NSA to get inside. Intel Inside It’s inevitable that complex microprocessors have bugs in them when they ship. When the first microprocessors shipped the only thing you could hope is that the bug didn’t crash your computer. The only way the chip vendor could fix the problem was to physically revise the chip and put out a new version. But computer manufacturers and users were stuck if you had an old chip. After a particularly embarrassing math bug in 1994 that cost Intel $475 million, the company decided to fix the problem by allowing it’s microprocessors to load fixes automatically when your computer starts.
  • Starting in 1996 with the Intel P6 (Pentium Pro) to today’s P7 chips (Core i7) these processors contain instructions that are reprogrammable in what is called microcode. Intel can fix bugs on the chips by reprogramming a microprocessors microcode with a patch. This patch, called a microcode update, can be loaded into a processor by using special CPU instructions reserved for this purpose. These updates are not permanent, which means each time you turn the computer on, its microprocessor is reset to its built-in microcode, and the update needs to be applied again (through a computer’s BIOS.). Since 2000, Intel has put out 29 microcode updates to their processors. The microcode is distributed by 1) Intel or by 2) Microsoft integrated into a BIOS or 3) as part of a Windows update. Unfortunately, the microcode update format is undocumented and the code is encrypted. This allows Intel to make sure that 3rd parties can’t make unauthorized add-ons to their chips. But it also means that no one can look inside to understand the microcode, which makes it is impossible to know whether anyone is loading a backdoor into your computer.
  • ...3 more annotations...
  • Or perhaps the NSA, working with Intel and/or Microsoft, have wittingly have put backdoors in the microcode updates. A backdoor is is a way of gaining illegal remote access to a computer by getting around the normal security built-in to the computer. Typically someone trying to sneak malicious software on to a computer would try to install a rootkit (software that tries to conceal the malicious code.) A rootkit tries to hide itself and its code, but security conscious sites can discover rootkits by tools that check kernel code and data for changes. But what if you could use the configuration and state of microprocessor hardware in order to hide? You’d be invisible to all rootkit detection techniques that checks the operating system. Or what if you can make the microprocessor random number generator (the basis of encryption) not so random for a particular machine? (The NSA’s biggest coup was inserting backdoors in crypto equipment the Swiss sold to other countries.) Rather than risk getting caught messing with everyone’s updates, my bet is that the NSA has compromised the microcode update signing keys  giving the NSA the ability to selectively target specific computers. (Your operating system ensures security of updates by checking downloaded update packages against the signing key.) The NSA then can send out backdoors disguised as a Windows update for “security.” (Ironic but possible.) That means you don’t need backdoors baked in the hardware, don’t need Intel’s buy-in, don’t have discoverable rootkits, and you can target specific systems without impacting the public at large.
  • A few months ago these kind of discussions would have been theory at best, if not paranoia.
  • The Prism disclosures prove otherwise – the National Security Agency has decided it needs the ability to capture all communications in all forms. Getting inside of a target computer and weakening its encryption or having access to the plaintext of encrypted communication seems likely. Given the technical sophistication of the other parts of their surveillance net, the surprise would be if they haven’t implemented a microcode backdoor. The downside is that 1) backdoors can be hijacked by others with even worse intent. So if NSA has a microcode backdoor – who else is using it? and 2) What other pieces of our infrastructure, (routers, smartphones, military computers, satellites, etc) use processors with uploadable microcode? —— And that may be why the Russian president is now using a typewriter rather than a personal computer.

  • As fast as it can, Google is sealing up cracks in its systems that Edward J. Snowden revealed the N.S.A. had brilliantly exploited. It is encrypting more data as it moves among its servers and helping customers encode their own emails. Facebook, Microsoft and Yahoo are taking similar steps.
  • After years of cooperating with the government, the immediate goal now is to thwart Washington — as well as Beijing and Moscow. The strategy is also intended to preserve business overseas in places like Brazil and Germany that have threatened to entrust data only to local providers. Google, for example, is laying its own fiber optic cable under the world’s oceans, a project that began as an effort to cut costs and extend its influence, but now has an added purpose: to assure that the company will have more control over the movement of its customer data.
  • A year after Mr. Snowden’s revelations, the era of quiet cooperation is over. Telecommunications companies say they are denying requests to volunteer data not covered by existing law. A.T.&T., Verizon and others say that compared with a year ago, they are far more reluctant to cooperate with the United States government in “gray areas” where there is no explicit requirement for a legal warrant.

  • Eric Grosse, Google’s security chief, suggested in an interview that the N.S.A.'s own behavior invited the new arms race.“I am willing to help on the purely defensive side of things,” he said, referring to Washington’s efforts to enlist Silicon Valley in cybersecurity efforts. “But signals intercept is totally off the table,” he said, referring to national intelligence gathering.“No hard feelings, but my job is to make their job hard,” he added.
  • Hardware firms like Cisco, which makes routers and switches, have found their products a frequent subject of Mr. Snowden’s disclosures, and their business has declined steadily in places like Asia, Brazil and Europe over the last year. The company is still struggling to convince foreign customers that their networks are safe from hackers — and free of “back doors” installed by the N.S.A. The frustration, companies here say, is that it is nearly impossible to prove that their systems are N.S.A.-proof.
  • In Washington, officials acknowledge that covert programs are now far harder to execute because American technology companies, fearful of losing international business, are hardening their networks and saying no to requests for the kind of help they once quietly provided.Continue reading the main story Robert S. Litt, the general counsel of the Office of the Director of National Intelligence, which oversees all 17 American spy agencies, said on Wednesday that it was “an unquestionable loss for our nation that companies are losing the willingness to cooperate legally and voluntarily” with American spy agencies.
  • Mr. Smith also said the company was setting up “transparency centers” abroad so that technical experts of foreign governments could come in and inspect Microsoft’s proprietary source code. That will allow foreign governments to check to make sure there are no “back doors” that would permit snooping by United States intelligence agencies. The first such center is being set up in Brussels.Microsoft has also pushed back harder in court. In a Seattle case, the government issued a “national security letter” to compel Microsoft to turn over data about a customer, along with a gag order to prevent Microsoft from telling the customer it had been compelled to provide its communications to government officials. Microsoft challenged the gag order as violating the First Amendment. The government backed down.
  • Many point to an episode in 2012, when Russian security researchers uncovered a state espionage tool, Flame, on Iranian computers. Flame, like the Stuxnet worm, is believed to have been produced at least in part by American intelligence agencies. It was created by exploiting a previously unknown flaw in Microsoft’s operating systems. Companies argue that others could have later taken advantage of this defect.Worried that such an episode undercuts confidence in its wares, Microsoft is now fully encrypting all its products, including Hotmail and Outlook.com, by the end of this year with 2,048-bit encryption, a stronger protection that would take a government far longer to crack. The software is protected by encryption both when it is in data centers and when data is being sent over the Internet, said Bradford L. Smith, the company’s general counsel.
  • In one slide from the disclosures, N.S.A. analysts pointed to a sweet spot inside Google’s data centers, where they could catch traffic in unencrypted form. Next to a quickly drawn smiley face, an N.S.A. analyst, referring to an acronym for a common layer of protection, had noted, “SSL added and removed here!”
  • Facebook and Yahoo have also been encrypting traffic among their internal servers. And Facebook, Google and Microsoft have been moving to more strongly encrypt consumer traffic with so-called Perfect Forward Secrecy, specifically devised to make it more labor intensive for the N.S.A. or anyone to read stored encrypted communications.One of the biggest indirect consequences from the Snowden revelations, technology executives say, has been the surge in demands from foreign governments that saw what kind of access to user information the N.S.A. received — voluntarily or surreptitiously. Now they want the same.
  • The latest move in the war between intelligence agencies and technology companies arrived this week, in the form of a new Google encryption tool. The company released a user-friendly, email encryption method to replace the clunky and often mistake-prone encryption schemes the N.S.A. has readily exploited.But the best part of the tool was buried in Google’s code, which included a jab at the N.S.A.'s smiley-face slide. The code included the phrase: “ssl-added-and-removed-here-; - )”

Google Says Website Encryption Will Now Influence Search Rankings - 0 views

surveillance state NSA-reform NSA-blowback Google

shared by Paul Merrell on 08 Aug 14 - No Cached
  • Google will begin using website encryption, or HTTPS, as a ranking signal – a move which should prompt website developers who have dragged their heels on increased security measures, or who debated whether their website was “important” enough to require encryption, to make a change. Initially, HTTPS will only be a lightweight signal, affecting fewer than 1% of global queries, says Google. That means that the new signal won’t carry as much weight as other factors, including the quality of the content, the search giant noted, as Google means to give webmasters time to make the switch to HTTPS. Over time, however, encryption’s effect on search ranking make strengthen, as the company places more importance on website security. Google also promises to publish a series of best practices around TLS (HTTPS, is also known as HTTP over TLS, or Transport Layer Security) so website developers can better understand what they need to do in order to implement the technology and what mistakes they should avoid. These tips will include things like what certificate type is needed, how to use relative URLs for resources on the same secure domain, best practices around allowing for site indexing, and more.
  • In addition, website developers can test their current HTTPS-enabled website using the Qualys Lab tool, says Google, and can direct further questions to Google’s Webmaster Help Forums where the company is already in active discussions with the broader community. The announcement has drawn a lot of feedback from website developers and those in the SEO industry – for instance, Google’s own blog post on the matter, shared in the early morning hours on Thursday, is already nearing 1,000 comments. For the most part, the community seems to support the change, or at least acknowledge that they felt that something like this was in the works and are not surprised. Google itself has been making moves to better securing its own traffic in recent months, which have included encrypting traffic between its own servers. Gmail now always uses an encrypted HTTPS connection which keeps mail from being snooped on as it moves from a consumer’s machine to Google’s data centers.
  • While HTTPS and site encryption have been a best practice in the security community for years, the revelation that the NSA has been tapping the cables, so to speak, to mine user information directly has prompted many technology companies to consider increasing their own security measures, too. Yahoo, for example, also announced in November its plans to encrypt its data center traffic. Now Google is helping to push the rest of the web to do the same.
