HTTP/2 is getting close to being real, with lots of discussions and more implementations popping up every week. What does a new version of the Web’s protocol mean for you? Here are some early answers:

“A program obfuscator would be a powerful tool for finding plausible constructions for just about any cryptographic task you could conceive of,” said Yuval Ishai, of the Technion in Haifa, Israel. Precisely because of obfuscation’s power, many computer scientists, including Sahai and his colleagues, thought it was impossible. “We were convinced it was too powerful to exist,” he said. Their earliest research findings seemed to confirm this, showing that the most natural form of obfuscation is indeed impossible to achieve for all programs. Then, on July 20, 2013, Sahai and five co-authors posted a paper on the Cryptology ePrint Archive demonstrating a candidate protocol for a kind of obfuscation known as “indistinguishability obfuscation.” Two days later, Sahai and one of his co-authors, Brent Waters, of the University of Texas, Austin, posted a second paper that suggested, together with the first paper, that this somewhat arcane form of obfuscation may possess much of the power cryptographers have dreamed of. “This is the first serious positive result” when it comes to trying to find a universal obfuscator, said Boaz Barak, of Microsoft Research in Cambridge, Mass. “The cryptography community is very excited.” In the six months since the original paper was posted, more papers have appeared on the ePrint archive with “obfuscation” in the title than in the previous 17 years.

Federal Magistrate Judge John M. Facciola denied a US government request earlier this month for a search and seizure warrant, targeting electronic data stored on Apple Inc. property. Facciola’s order, issued on March 7, 2014, rejected what it described as only the latest in a series of “overbroad search and seizure requests,” and “unconstitutional warrant applications” submitted by the US government to the US District Court for the District of Columbia. Facciola referred to the virtually unlimited warrant request submitted by the Justice Department as “repugnant to the Fourth Amendment.” The surveillance request sought information in relation to a “kickback investigation” of a defense contractor, details about which remain secret. It is significant, however, that the surveillance request denied by Facciola relates to a criminal investigation, unrelated to terrorism. This demonstrates that the use by the Obama administration of blanket warrants enabling them to seize all information on a person's Internet accounts is not limited to terrorism, as is frequently claimed, but is part of a program of general mass illegal spying on the American people.

Facciola’s ruling states in no uncertain terms that the Obama administration has aggressively and repeatedly sought expansive, unconstitutional warrants, ignoring the court’s insistence for specific, narrowly targeted surveillance requests. “The government continues to submit overly broad warrants and makes no effort to balance the law enforcement interest against the obvious expectation of privacy email account holders have in their communications…The government continues to ask for all electronically stored information in email accounts, irrespective of the relevance to the investigation,” wrote Judge Facciola. As stated in the ruling, the surveillance requests submitted to the court by the US government sought the following comprehensive, virtually limitless list of information about the target: “All records or other information stored by an individual using each account, including address books, contact and buddy lists, pictures, and files… All records or other information regarding the identification of the accounts, to include full name, physical address, telephone numbers and other identifies, records of session times and durations, the date on which each account was created, the length of service, the types of service utilized, the Internet Protocol (IP) address used to register each account, log-in IP addresses associated with session times and dates, account status, alternative email addresses provided during registration, methods of connecting, log files, and means of payment (including any credit or bank account number).”

Responding to these all-encompassing warrant requests, Judge Facciola ruled that evidence of probable cause was necessary for each specific item sought by the government. “This Court is increasingly concerned about the government’s applications for search warrants for electronic data. In essence, its applications ask for the entire universe of information tied to a particular account, even if it has established probable cause only for certain information,” Facciola wrote. “It is the Court’s duty to reject any applications for search warrants where the standard of probable cause has not been met… To follow the dictates of the Fourth Amendment and to avoid issuing a general warrant, a court must be careful to ensure that probable cause exists to seize each item specified in the warrant application… Any search of an electronic source has the potential to unearth tens or hundreds of thousands of individual documents, pictures, movies, or other constitutionally protected content.” Facciola also noted in the ruling that the government never reported the length of time it would keep the data, or whether it planned to destroy the data at any point.

This month, the United States District Court for the District of Columbia ruled that the Department of Homeland Security must make its plan to shut off the Internet and cellphone communications available to the American public. You, of course, may now be thinking: What plan?! Though President Barack Obama swiftly disapproved of ousted Egyptian President Hosni Mubarak turning off the Internet in his country (to quell widespread civil disobedience) in 2011, the US government has the authority to do the same sort of thing, under a plan that was devised during the George W. Bush administration. Many details of the government’s controversial “kill switch” authority have been classified, such as the conditions under which it can be implemented and how the switch can be used. But thanks to a Freedom of Information Act lawsuit filed by the Electronic Privacy Information Center (EPIC), DHS has to reveal those details by December 12 — or mount an appeal. (The smart betting is on an appeal, since DHS has fought to release this information so far.) Yet here’s what we do know about the government’s “kill switch” plan:

What are the constitutional problems? Civil liberties advocates argue that kill switches violate the First Amendment and pose a problem because they aren’t subject to rigorous judicial and congressional oversight. “There is no court in the loop at all, at any stage in the SOP 303 process,” according to the Center for Democracy and Technology. ”The executive branch, untethered by the checks and balances of court oversight, clear instruction from Congress, or transparency to the public, is free to act as it will and in secret.” David Jacobs of EPIC says, “Cutting off communications imposes a prior restraint on speech, so the First Amendment imposes the strictest of limitations…We don’t know how DHS thinks [the kill switch] is consistent with the First Amendment.” He adds, “Such a policy, unbounded by clear rules and oversight, just invites abuse.”

April 21, 2015 Dear Chairman Goodlatte, Ranking Member Conyers, Chairman Grassley, and Ranking Member Leahy: We urge you to end mass surveillance of Americans. Among us are civil liberties organizations from across the political spectrum that speak for millions of people, businesses, whistleblowers, and experts. The impending expiration of three USA PATRIOT Act provisions on June 1 is a golden opportunity to end mass surveillance and enact additional reforms. Current surveillance practices are virtually limitless. They are unnecessary, counterproductive, and costly. They undermine our economy and the public’s trust in government. And they undercut the proper functioning of government. Meaningful surveillance reform entails congressional repeal of laws and protocols the Executive secretly interprets to permit current mass surveillance practices. Additionally, it requires Congress to appreciably increase transparency, oversight, and accountability of intelligence agencies, especially those that have acted unconstitutionally.

A majority of the House of Representatives already has voted against mass surveillance. The Massie-Lofgren amendment to the National Defense Authorization Act [i] garnered 293 votes in support of defunding “backdoor searches.” Unfortunately, that amendment was not included in the “CRomnibus"[ii] despite overwhelming support.  We urge you to act once again to vindicate our fundamental liberties.

Former US intelligence contractor Edward Snowden’s revelations rocked the world.  According to his detailed reports, the US had launched massive spying programs and was scrutinizing the communications of American citizens in a manner which could only be described as extreme and intense. The US’s reaction was swift and to the point. “”Nobody is listening to your telephone calls,” President Obama said when asked about the NSA. As quoted in The Guardian,  Obama went on to say that surveillance programs were “fully overseen not just by Congress but by the Fisa court, a court specially put together to evaluate classified programs to make sure that the executive branch, or government generally, is not abusing them”. However, it appears that Snowden may have missed a pivotal part of the US surveillance program. And in stating that the “nobody” is not listening to our calls, President Obama may have been fudging quite a bit.

In fact, Great Britain maintains a “listening post” at NSA HQ. The laws restricting live wiretaps do not apply to foreign countries  and thus this listening post  is not subject to  US law.  In other words, the restrictions upon wiretaps, etc. do not apply to the British listening post.  So when Great Britain hands over the recordings to the NSA, technically speaking, a law is not being broken and technically speaking, the US is not eavesdropping on our each and every call. It is Great Britain which is doing the eavesdropping and turning over these records to US intelligence. According to John Loftus, formerly an attorney with  the Department of Justice and author of a number of books concerning US intelligence activities, back in the late seventies  the USDOJ issued a memorandum proposing an amendment to FISA. Loftus, who recalls seeing  the memo, stated in conversation this week that the DOJ proposed inserting the words “by the NSA” into the FISA law  so the scope of the law would only restrict surveillance by the NSA, not by the British.  Any subsequent sharing of the data culled through the listening posts was strictly outside the arena of FISA. Obama was less than forthcoming when he insisted that “What I can say unequivocally is that if you are a US person, the NSA cannot listen to your telephone calls, and the NSA cannot target your emails … and have not.”

According to Loftus, the NSA is indeed listening as Great Britain is turning over the surveillance records en masse to that agency. Loftus states that the arrangement is reciprocal, with the US maintaining a parallel listening post in Great Britain. In an interview this past week, Loftus told this reporter that  he believes that Snowden simply did not know about the arrangement between Britain and the US. As a contractor, said Loftus, Snowden would not have had access to this information and thus his detailed reports on the extent of US spying, including such programs as XKeyscore, which analyzes internet data based on global demographics, and PRISM, under which the telecommunications companies, such as Google, Facebook, et al, are mandated to collect our communications, missed the critical issue of the FISA loophole.

The National Security Agency and its British counterpart, Government Communications Headquarters, have worked to subvert anti-virus and other security software in order to track users and infiltrate networks, according to documents from NSA whistleblower Edward Snowden. The spy agencies have reverse engineered software products, sometimes under questionable legal authority, and monitored web and email traffic in order to discreetly thwart anti-virus software and obtain intelligence from companies about security software and users of such software. One security software maker repeatedly singled out in the documents is Moscow-based Kaspersky Lab, which has a holding registered in the U.K., claims more than 270,000 corporate clients, and says it protects more than 400 million people with its products. British spies aimed to thwart Kaspersky software in part through a technique known as software reverse engineering, or SRE, according to a top-secret warrant renewal request. The NSA has also studied Kaspersky Lab’s software for weaknesses, obtaining sensitive customer information by monitoring communications between the software and Kaspersky servers, according to a draft top-secret report. The U.S. spy agency also appears to have examined emails inbound to security software companies flagging new viruses and vulnerabilities.

The efforts to compromise security software were of particular importance because such software is relied upon to defend against an array of digital threats and is typically more trusted by the operating system than other applications, running with elevated privileges that allow more vectors for surveillance and attack. Spy agencies seem to be engaged in a digital game of cat and mouse with anti-virus software companies; the U.S. and U.K. have aggressively probed for weaknesses in software deployed by the companies, which have themselves exposed sophisticated state-sponsored malware.

The requested warrant, provided under Section 5 of the U.K.’s 1994 Intelligence Services Act, must be renewed by a government minister every six months. The document published today is a renewal request for a warrant valid from July 7, 2008 until January 7, 2009. The request seeks authorization for GCHQ activities that “involve modifying commercially available software to enable interception, decryption and other related tasks, or ‘reverse engineering’ software.”

In a Chicago court, several Facebook users filed a class-action lawsuit against the social media giant for allegedly violating its users’ privacy rights to acquire the largest privately held stash of biometric face-recognition data in the world. The court documents reveal claims that “Facebook began violating the Illinois Biometric Information Privacy Act (IBIPA) of 2008 in 2010, in a purported attempt to make the process of tagging friends easier.”

This was accomplished through the “tag suggestions” feature provided by Facebook which “scans all pictures uploaded by users and identifies any Facebook friends they may want to tag.” The Facebook users maintain that this feature is a “form of data mining [that] violates user’s privacy”. One plaintiff said this is a “brazen disregard for its users’ privacy rights,” through which Facebook has “secretly amassed the world’s largest privately held database of consumer biometrics data.” Because “Facebook actively conceals” their protocol using “faceprint databases” to identify Facebook users in photos, and “doesn’t disclose its wholesale biometrics data collection practices in its privacy policies, nor does it even ask users to acknowledge them.”

This would be a violation of the IBIPA which states it is “unlawful to collect biometric data without written notice to the subject stating the purpose and length of the data collection, and without obtaining the subject’s written release.” Because all users are automatically part of the “faceprint’ facial recognition program, this is an illegal act in the state of Illinois, according to the complaint. Jay Edelson, attorney for the plaintiffs, asserts the opt-out ability to prevent other Facebook users from tagging them in photos is “insufficient”.

The unique nature of the spectrum makes designing networking algorithms and protocols a challenge. There are several digital TV white spaces in the band, and the demands of access points vary over time. "Since in a TV band you don’t get continuous contiguous spectrum—a typical white-space chunk has 6 MHz—you need at least two radios to tune to different bandwidths. Our algorithms decide which radio will choose which bandwidth," says Srinivasan.

The two providers want to lay the crumbling POTS to rest and replace it with Internet Protocol-based systems that use the same wired and wireless broadband networks that bring Web access, cable programming and, yes, even your telephone service, into your homes. You may think you have a traditional landline because your home phone plugs into a jack, but if you have bundled your phone with Internet and cable services, you're making calls over an IP network, not twisted copper wires. California, Florida, Texas, Georgia, North Carolina, Wisconsin and Ohio are among states that agree telecom resources would be better redirected into modern telephone technologies and innovations, and will kill copper-based technologies in the next three years or so. Kentucky and Colorado are weighing similar laws, which force people to go wireless whether they want to or not. In Mantoloking, N.J., Verizon wants to replace the landline system, which Hurricane Sandy wiped out, with its wireless Voice Link. That would make it the first entire town to go landline-less, a move that isn't sitting well with all residents.

New Jersey's legislature, worried about losing data applications such as credit-card processing and alarm systems that wireless systems can't handle, wants a one-year moratorium to block that switch. It will vote on the measure this month. (Verizon tried a similar change in Fire Island, N.Y., when its copper lines were destroyed, but public opposition persuaded Verizon to install fiber-optic cable.) It's no surprise that landlines are unfashionable, considering many of us already have or are preparing to ditch them. More than 38% of adults and 45.5% of children live in households without a landline telephone, says the Centers for Disease Control and Prevention. That means two in every five U.S. homes, or 39%, are wireless, up from 26.6% three years ago. Moreover, a scant 8.5% of households relied only on a landline, while 2% were phoneless in 2013. Metropolitan residents have few worries about the end of landlines. High-speed wire and wireless services are abundant and work well, despite occasional dropped calls. Those living in rural areas, where cell towers are few and 4G capability limited, face different issues.

In the absence of real reform, people and institutions at home and abroad are taking matters into their own hands. In America, the NSA’s overreach is changing the way we communicate with and relate to each other. In order to evade government surveillance, more and more Americans are employing encryption technology.  The veritable explosion of new secure messaging apps like Surespot, OpenWhisper’s collaboration with WhatsApp, the development and deployment of open source anti-surveillance tools like Detekt, the creation of organizationally-sponsored “surveillance self-defense” guides, the push to universalize the https protocol, anti-surveillance book events featuring free encryption workshops— are manifestations of the rise of the personal encryption and pro-privacy digital resistance movement. Its political implications are clear: Americans, along with people around the world, increasingly see the United States government’s overreaching surveillance activities as a threat to be blocked.

The federal government’s vacuum-cleaner approach to surveillance—manifested in Title II of the PATRIOT Act, the FISA Amendments Act, and EO 12333—has backfired in these respects, and the emergence of this digital resistance movement is one result. Indeed, the existence and proliferation of social networks hold the potential to help this movement spread faster and to more of the general public than would have been possible in decades past. This is evidenced by the growing concern worldwide about governments’ ability to access reams of information about people’s lives with relative ease. As one measure, compared to a year ago, 41% of online users in North America now avoid certain Internet sites and applications, 16% change who they communicate with, and 24% censor what they say online. Those numbers, if anywhere close to accurate, are a major concern for democratic society.

Even if commercially available privacy technology proves capable of providing a genuine shield against warrantless or otherwise illegal surveillance by the United States government, it will remain a treatment for the symptom, not a cure for the underlying legal and constitutional malady. In April 2014, a Harris poll of US adults showed that in response to the Snowden revelations, “Almost half of respondents (47%) said that they have changed their online behavior and think more carefully about where they go, what they say, and what they do online.” Set aside for a moment that just the federal government’s collection of the data of innocent Americans is itself likely a violation of the Fourth Amendment. The Harris poll is just one of numerous studies highlighting the collateral damage to American society and politics from NSA’s excesses: segments of our population are now fearful of even associating with individuals or organizations executive branch officials deem controversial or suspicious. Nearly half of Americans say they have changed their online behavior out of a fear of what the federal government might do with their personal information. The Constitution’s free association guarantee has been damaged by the Surveillance State’s very operation.

Micah Lee: What are some operational security practices you think everyone should adopt? Just useful stuff for average people. Edward Snowden: [Opsec] is important even if you’re not worried about the NSA. Because when you think about who the victims of surveillance are, on a day-to-day basis, you’re thinking about people who are in abusive spousal relationships, you’re thinking about people who are concerned about stalkers, you’re thinking about children who are concerned about their parents overhearing things. It’s to reclaim a level of privacy. The first step that anyone could take is to encrypt their phone calls and their text messages. You can do that through the smartphone app Signal, by Open Whisper Systems. It’s free, and you can just download it immediately. And anybody you’re talking to now, their communications, if it’s intercepted, can’t be read by adversaries. [Signal is available for iOS and Android, and, unlike a lot of security tools, is very easy to use.] You should encrypt your hard disk, so that if your computer is stolen the information isn’t obtainable to an adversary — pictures, where you live, where you work, where your kids are, where you go to school. [I’ve written a guide to encrypting your disk on Windows, Mac, and Linux.] Use a password manager. One of the main things that gets people’s private information exposed, not necessarily to the most powerful adversaries, but to the most common ones, are data dumps. Your credentials may be revealed because some service you stopped using in 2007 gets hacked, and your password that you were using for that one site also works for your Gmail account. A password manager allows you to create unique passwords for every site that are unbreakable, but you don’t have the burden of memorizing them. [The password manager KeePassX is free, open source, cross-platform, and never stores anything in the cloud.]

The other thing there is two-factor authentication. The value of this is if someone does steal your password, or it’s left or exposed somewhere … [two-factor authentication] allows the provider to send you a secondary means of authentication — a text message or something like that. [If you enable two-factor authentication, an attacker needs both your password as the first factor and a physical device, like your phone, as your second factor, to login to your account. Gmail, Facebook, Twitter, Dropbox, GitHub, Battle.net, and tons of other services all support two-factor authentication.]

We should armor ourselves using systems we can rely on every day. This doesn’t need to be an extraordinary lifestyle change. It doesn’t have to be something that is disruptive. It should be invisible, it should be atmospheric, it should be something that happens painlessly, effortlessly. This is why I like apps like Signal, because they’re low friction. It doesn’t require you to re-order your life. It doesn’t require you to change your method of communications. You can use it right now to talk to your friends.
