– Cluster Coefficient: This will give you an idea of how cohesive your network is. It’s pretty simple, just how many links you have in your network as a percentage of total potential links (which you can calculate by n(n-1)/2)

Finally, I would encourage you to read “6 Degrees” by Watts and “Linked” by Barabasi. Both are primary network theory pioneers and give accounts that are much more readable and informative than journalists write.

A tribe would eventually choose a host based on convenience (members are already using it, easy navigation, rapid sharing of communication, etc.), integration (Facebook Connect, Google Connect), and to some extent, available applications for members to use while being logged on to the network. Facebook excels in all three

The National Federation of the Blind is applauding the decisions of Syracuse University and the University of Wisconsin-Madison not to Amazon.com's Kindle DX as a textbook replacement.

"The big disappointment was learning that the Kindle DX is not accessible to the blind," Ken Frazier, the University of Wisconsin-Madison director of libraries, said in a statement. "Advancements in text-to-speech technology have created a market opportunity for an e-book reading device that is fully accessible for everyone. This version of the Kindle e-book reader missed the mark."

Following up on its announcement at The Cable Show last month, Cox Communications is now offering more detail on the company's pending rollout of gigabit broadband services throughout its territories. (See Cox Goes for a Gigabit .) Cox Communications Inc. is targeting Phoenix, Las Vegas, and Omaha as its first new gigabit markets and plans to begin deployments across its entire footprint by the end of 2016. In addition to residential home service, the company will offer gigabit connectivity to select condominiums and apartments and will expand WiFi service both in common areas of those multi-dwelling units (MDU) and in public locations across the Phoenix and Las Vegas metro areas. The announcement by Cox, the first major North American MSO to make a 1-Gig commitment throughout its footprint, follows a recent pattern of competitive announcements from broadband service providers. Typically, one operator introduces or says it will explore delivery of higher broadband speeds, and then other local providers rapidly follow suit. In February, for instance, Google Fiber Inc. said it would look at expanding fiber service to 34 new cities, including Phoenix, where it will compete against Cox for the first time. (See Google Fiber Shifts Into High Gear.)

At the same time, CenturyLink Inc. (NYSE: CTL) began offering gigabit service in Las Vegas last fall and in Omaha last May, putting Cox on the hot seat in those two markets as well. This isn't Cox's first venture into gigabit broadband service. In addition to providing gigabit connections to commercial customers, the operator started a fiber-to-the-home trial service in Orange County, Calif. last year. For the company's upcoming deployments, a spokesperson noted that Cox hasn't yet specified which technologies it will use, but said that it will rely on portions of Cox's existing network in addition to newer fiber infrastructure.

Email encryption in transit Many email providers don’t encrypt messages while they’re in transit. When you send or receive emails with one of these providers, these messages are as open to snoopers as a postcard in the mail. A growing number of email providers are working to change that, by encrypting messages sent to and from our services using Transport Layer Security (TLS). When an email is encrypted in transit with TLS, it makes it harder for others to read what you’re sending. The data below explains the current state of email encryption in transit.

Generally speaking, use of encryption in transit increases over time, as more providers enable and maintain their support. Factors such as varying volumes of email may explain other fluctuations.

Below is the percentage of email encrypted for the top domains in terms of volume of email to and from Gmail, in alphabetical order.

The United Nations’ top official for counter-terrorism and human rights (known as the “Special Rapporteur”) issued a formal report to the U.N. General Assembly today that condemns mass electronic surveillance as a clear violation of core privacy rights guaranteed by multiple treaties and conventions. “The hard truth is that the use of mass surveillance technology effectively does away with the right to privacy of communications on the Internet altogether,” the report concluded. Central to the Rapporteur’s findings is the distinction between “targeted surveillance” — which “depend[s] upon the existence of prior suspicion of the targeted individual or organization” — and “mass surveillance,” whereby “states with high levels of Internet penetration can [] gain access to the telephone and e-mail content of an effectively unlimited number of users and maintain an overview of Internet activity associated with particular websites.” In a system of “mass surveillance,” the report explained, “all of this is possible without any prior suspicion related to a specific individual or organization. The communications of literally every Internet user are potentially open for inspection by intelligence and law enforcement agencies in the States concerned.”

Mass surveillance thus “amounts to a systematic interference with the right to respect for the privacy of communications,” it declared. As a result, “it is incompatible with existing concepts of privacy for States to collect all communications or metadata all the time indiscriminately.” In concluding that mass surveillance impinges core privacy rights, the report was primarily focused on the International Covenant on Civil and Political Rights, a treaty enacted by the General Assembly in 1966, to which all of the members of the “Five Eyes” alliance are signatories. The U.S. ratified the treaty in 1992, albeit with various reservations that allowed for the continuation of the death penalty and which rendered its domestic law supreme. With the exception of the U.S.’s Persian Gulf allies (Saudi Arabia, UAE and Qatar), virtually every major country has signed the treaty. Article 17 of the Covenant guarantees the right of privacy, the defining protection of which, the report explained, is “that individuals have the right to share information and ideas with one another without interference by the State, secure in the knowledge that their communication will reach and be read by the intended recipients alone.”

The report’s key conclusion is that this core right is impinged by mass surveillance programs: “Bulk access technology is indiscriminately corrosive of online privacy and impinges on the very essence of the right guaranteed by article 17. In the absence of a formal derogation from States’ obligations under the Covenant, these programs pose a direct and ongoing challenge to an established norm of international law.” The report recognized that protecting citizens from terrorism attacks is a vital duty of every state, and that the right of privacy is not absolute, as it can be compromised when doing so is “necessary” to serve “compelling” purposes. It noted: “There may be a compelling counter-terrorism justification for the radical re-evaluation of Internet privacy rights that these practices necessitate. ” But the report was adamant that no such justifications have ever been demonstrated by any member state using mass surveillance: “The States engaging in mass surveillance have so far failed to provide a detailed and evidence-based public justification for its necessity, and almost no States have enacted explicit domestic legislation to authorize its use.”

A Message from the Amazon Books Team Dear Readers, Just ahead of World War II, there was a radical invention that shook the foundations of book publishing. It was the paperback book. This was a time when movie tickets cost 10 or 20 cents, and books cost $2.50. The new paperback cost 25 cents — it was ten times cheaper. Readers loved the paperback and millions of copies were sold in just the first year. With it being so inexpensive and with so many more people able to afford to buy and read books, you would think the literary establishment of the day would have celebrated the invention of the paperback, yes? Nope. Instead, they dug in and circled the wagons. They believed low cost paperbacks would destroy literary culture and harm the industry (not to mention their own bank accounts). Many bookstores refused to stock them, and the early paperback publishers had to use unconventional methods of distribution — places like newsstands and drugstores. The famous author George Orwell came out publicly and said about the new paperback format, if "publishers had any sense, they would combine against them and suppress them." Yes, George Orwell was suggesting collusion. Well… history doesn't repeat itself, but it does rhyme.

Fast forward to today, and it's the e-book's turn to be opposed by the literary establishment. Amazon and Hachette — a big US publisher and part of a $10 billion media conglomerate — are in the middle of a business dispute about e-books. We want lower e-book prices. Hachette does not. Many e-books are being released at $14.99 and even $19.99. That is unjustifiably high for an e-book. With an e-book, there's no printing, no over-printing, no need to forecast, no returns, no lost sales due to out of stock, no warehousing costs, no transportation costs, and there is no secondary market — e-books cannot be resold as used books. E-books can and should be less expensive. Perhaps channeling Orwell's decades old suggestion, Hachette has already been caught illegally colluding with its competitors to raise e-book prices. So far those parties have paid $166 million in penalties and restitution. Colluding with its competitors to raise prices wasn't only illegal, it was also highly disrespectful to Hachette's readers. The fact is many established incumbents in the industry have taken the position that lower e-book prices will "devalue books" and hurt "Arts and Letters." They're wrong. Just as paperbacks did not destroy book culture despite being ten times cheaper, neither will e-books. On the contrary, paperbacks ended up rejuvenating the book industry and making it stronger. The same will happen with e-books.

Software created by the controversial UK-based Gamma Group International was used to spy on computers that appear to be located in the United States, the UK, Germany, Russia, Iran, and Bahrain, according to a leaked trove of documents analyzed by ProPublica. It's not clear whether the surveillance was conducted by governments or private entities. Customer e-mail addresses in the collection appeared to belong to a German surveillance company, an independent consultant in Dubai, the Bosnian and Hungarian Intelligence services, a Dutch law enforcement officer, and the Qatari government.

The leaked files—which were posted online by hackers—are the latest in a series of revelations about how state actors including repressive regimes have used Gamma's software to spy on dissidents, journalists, and activist groups. The documents, leaked last Saturday, could not be readily verified, but experts told ProPublica they believed them to be genuine. "I think it's highly unlikely that it's a fake," said Morgan Marquis-Bore, a security researcher who while at The Citizen Lab at the University of Toronto had analyzed Gamma Group's software and who authored an article about the leak on Thursday. The documents confirm many details that have already been reported about Gamma, such as that its tools were used to spy on Bahraini activists. Some documents in the trove contain metadata tied to e-mail addresses of several Gamma employees. Bill Marczak, another Gamma Group expert at the Citizen Lab, said that several dates in the documents correspond to publicly known events—such as the day that a particular Bahraini activist was hacked.

The leaked files contain more than 40 gigabytes of confidential technical material, including software code, internal memos, strategy reports, and user guides on how to use Gamma Group software suite called FinFisher. FinFisher enables customers to monitor secure Web traffic, Skype calls, webcams, and personal files. It is installed as malware on targets' computers and cell phones. A price list included in the trove lists a license of the software at almost $4 million. The documents reveal that Gamma uses technology from a French company called Vupen Security that sells so-called computer "exploits." Exploits include techniques called "zero days" for "popular software like Microsoft Office, Internet Explorer, Adobe Acrobat Reader, and many more." Zero days are exploits that have not yet been detected by the software maker and therefore are not blocked.

Popular messaging services like Snapchat and WhatsApp are in the cross hairs in Britain. That was the message delivered on Monday by Prime Minister David Cameron, who said he would pursue banning encrypted messaging services if Britain’s intelligence services were not given access to the communications. The statement comes as many European politicians are demanding that Internet companies like Google and Facebook provide greater information about people’s online activities after several recent terrorist threats, including the attacks in Paris.

Mr. Cameron, who has started to campaign ahead of a national election in Britain in May, said his government, if elected, would ban encrypted online communication tools that could potentially be used by terrorists if the country’s intelligence agencies were not given increased access. The reforms are part of new legislation that would force telecom operators and Internet services providers to store more data on people’s online activities, including social network messages. “Are we going to allow a means of communications which it simply isn’t possible to read?” Mr. Cameron said at an event on Monday, in reference to services like WhatsApp, Snapchat and other encrypted online applications. “My answer to that question is: ‘No, we must not.’ ” Mr. Cameron said his first duty was to protect the country against terrorist attacks.

“The attacks in Paris demonstrated the scale of the threat that we face and the need to have robust powers through our intelligence and security agencies in order to keep our people safe,” he added. Any restriction on these online services, however, would not take effect until 2016, at the earliest, and it remained unclear how the British government could stop people from using these apps, which are used by hundreds of millions of people worldwide.

Verizon says it will soon offer customers a way to opt out from having their smartphone and tablet browsing tracked via a hidden un-killable tracking identifier. The decision came after a ProPublica article revealed that an online advertiser, Turn, was exploiting the Verizon identifier to respawn tracking cookies that users had deleted. Two days after the article appeared, Turn said it would suspend the practice of creating so-called "zombie cookies" that couldn't be deleted. But Verizon couldn't assure users that other companies might not also exploit the number - which was transmitted automatically to any website or app a user visited from a Verizon-enabled device - to build dossiers about people's behavior on their mobile devices. Verizon subsequently updated its website to note Turn's decision and declared that it would "work with other partners to ensure that their use of [the undeletable tracking number] is consistent with the purposes we intended." Previously, its website had stated: "It is unlikely that sites and ad entities will attempt to build customer profiles.

However, policing the hundreds of companies in the online tracking business was likely to be a difficult task for Verizon. And so, on Monday, Verizon followed in the footsteps of AT&T, which had already declared in November that it would stop inserting the hidden undeletable number in its users' Web traffic. In a statement emailed to reporters on Friday, Verizon said, "We have begun working to expand the opt-out to include the identifier referred to as the UIDH, and expect that to be available soon." Previously, users who opted out from Verizon's program were told that information about their demographics and Web browsing behavior would no longer be shared with advertisers, but that the tracking number would still be attached to their traffic. For more coverage, read ProPublica's previous reporting on Verizon's indestructible tracking and how one company used the tool to create zombie cookies.

The government has now filed its Second Circuit brief in the dispute with Microsoft (discussed here, here, and here), challenging key assertions by Microsoft and its many amici, and making a strong argument that a warrant issued under the Stored Communications Act (SCA) requires Microsoft to turn over emails in its custody and control, regardless of whether they are being held (in this case in Dublin). After reading the government’s brief, I am increasingly convinced that nothing in the text, structure, purpose, or legislative history provides a definitive answer to the central issue in the case (a point that the government implicitly concedes), and that, as a result, the dispute really is a policy one. Should, or should not, the government be authorized to compel Microsoft and other ISPs to produce emails of other private communications located in a foreign nation? What are the ramifications of such an answer on the United States’ ability to protect private communications — including that of its citizens — stored within its borders? And what are the implications for the government’s ability (or lack thereof) to access sought-after evidence overseas?

US Trade Representative Michael Froman is drawing fire from Congressional Democrats for the Obama adminstration’s continued imposition of secrecy surrounding the Trans-Pacific Parternship. (Photo: AP file) Democratic lawmaker says tightly-controlled briefings on Trans-Pacific Partnership deal are aimed at keeping US constituents ignorant about what’s at stake Lawmakers in Congress who remain wary of the Trans-Pacific Partnership (TPP) trade agreement are raising further objections this week to the degree of secrecy surrounding briefings on the deal, with some arguing that the main reason at least one meeting has been registered “classified” is to help keep the American public ignorant about giveaways to corporate interests and its long-term implications.

Among its other critics, Sen. Elizabeth Warren has slammed the idea of ISDS provisions as a surrender of democratic ideals to corporate interests. According to Warren, ISDS would simply “tilt the playing field in the United States further in favor of big multinational corporations.” By having unchallenged input on secretive TPP talks, Warren argued last month, these large companies and financial interests “are increasingly realizing this is an opportunity to gut U.S. regulations they don’t like.” According to Grayson, putting Wednesday’s ISDS briefing in a classified setting “is part of a multi-year campaign of deception and destruction. Why do we classify information? It’s to keep sensitive information out of the hands of foreign governments. In this case, foreign governments already have this information. They’re the people the administration is negotiating with. The only purpose of classifying this information is to keep it from the American people.”

“I’m not happy about it,” Rep. Alan Grayson (D-Fla.) told the Huffington Post, referring to the briefing with Froman and Labor Secretary Thomas Perez on Wednesday. The meeting—focused on the section of the TPP that deals with the controversial ‘Investor-State Dispute Settlement’ (ISDS) mechanism—has been labeled “classified,” so that lawmakers and any of their staff who attend will be barred, under threat of punishment, of revealing what they learn with constituents or outside experts. According to the Huffington Post: ISDS has been part of U.S. free trade agreements since NAFTA was signed into law in 1993, and has become a particularly popular tool for multinational firms over the past few years. But while the topic remains controversial, particularly with Democrats, many critics of the administration emphasize that applying national security-style restrictions on such information is an abuse of the classified information system. An additional meeting earlier on Wednesday on currency manipulation with Froman and Treasury Secretary Jack Lew is not classified.

When I first started reading Ars Technica, performance of a processor was measured in megahertz, and the major manufacturers were rushing to squeeze as many of them as possible into their latest silicon. Shortly thereafter, however, the energy needs and heat output of these beasts brought that race crashing to a halt. More recently, the number of processing cores rapidly scaled up, but they quickly reached the point of diminishing returns. Now, getting the most processing power for each Watt seems to be the key measure of performance. None of these things happened because the companies making processors ran up against hard physical limits. Rather, computing power ended up being constrained because progress in certain areas—primarily energy efficiency—was slow compared to progress in others, such as feature size. But could we be approaching physical limits in processing power? In this week's edition of Nature, The University of Michigan's Igor Markov takes a look at the sorts of limits we might face.

Alleged leaked documents about the NSA's XKeyscore snooping software appear to show the paranoid agency is targeting Tor and Tails users, Linux Journal readers – and anyone else interested in online privacy.Apparently, this configuration file for XKeyscore is in the divulged data, which was obtained and studied by members of the Tor project and security specialists for German broadcasters NDR and WDR. <a href="http://pubads.g.doubleclick.net/gampad/jump?iu=/6978/reg_security/front&sz=300x250%7C300x600&tile=3&c=33U7ZK6qwQrMkAACSrTugAAAP1&t=ct%3Dns%26unitnum%3D3%26unitname%3Dwww_top_mpu%26pos%3Dtop%26test%3D0" target="_blank"> <img src="http://pubads.g.doubleclick.net/gampad/ad?iu=/6978/reg_security/front&sz=300x250%7C300x600&tile=3&c=33U7ZK6qwQrMkAACSrTugAAAP1&t=ct%3Dns%26unitnum%3D3%26unitname%3Dwww_top_mpu%26pos%3Dtop%26test%3D0" alt=""></a> In their analysis of the alleged top-secret documents, they claim the NSA is, among other things:Specifically targeting Tor directory servers Reading email contents for mentions of Tor bridges Logging IP addresses used to search for privacy-focused websites and software And possibly breaking international law in doing so. We already know from leaked Snowden documents that Western intelligence agents hate Tor for its anonymizing abilities. But what the aforementioned leaked source code, written in a rather strange custom language, shows is that not only is the NSA targeting the anonymizing network Tor specifically, it is also taking digital fingerprints of any netizens who are remotely interested in privacy.

These include readers of the Linux Journal site, anyone visiting the website for the Tor-powered Linux operating system Tails – described by the NSA as "a comsec mechanism advocated by extremists on extremist forums" – and anyone looking into combining Tails with the encryption tool Truecrypt.If something as innocuous as Linux Journal is on the NSA's hit list, it's a distinct possibility that El Reg is too, particularly in light of our recent exclusive report on GCHQ – which led to a Ministry of Defence advisor coming round our London office for a chat.

If you take even the slightest interest in online privacy or have Googled a Linux Journal article about a broken package, you are earmarked in an NSA database for further surveillance, according to these latest leaks.This is assuming the leaked file is genuine, of course.Other monitored sites, we're told, include HotSpotShield, FreeNet, Centurian, FreeProxies.org, MegaProxy, privacy.li and an anonymous email service called MixMinion. The IP address of computer users even looking at these sites is recorded and stored on the NSA's servers for further analysis, and it's up to the agency how long it keeps that data.The XKeyscore code, we're told, includes microplugins that target Tor servers in Germany, at MIT in the United States, in Sweden, in Austria, and in the Netherlands. In doing so it may not only fall foul of German law but also the US's Fourth Amendment.

Today, 29 July 2014, WikiLeaks releases an unprecedented Australian censorship order concerning a multi-million dollar corruption case explicitly naming the current and past heads of state of Indonesia, Malaysia and Vietnam, their relatives and other senior officials. The super-injunction invokes “national security” grounds to prevent reporting about the case, by anyone, in order to “prevent damage to Australia's international relations”. The court-issued gag order follows the secret 19 June 2014 indictment of seven senior executives from subsidiaries of Australia's central bank, the Reserve Bank of Australia (RBA). The case concerns allegations of multi-million dollar inducements made by agents of the RBA subsidiaries Securency and Note Printing Australia in order to secure contracts for the supply of Australian-style polymer bank notes to the governments of Malaysia, Indonesia, Vietnam and other countries. Read the full press release here. Download the full Australia-wide censorship order for corruption case involving Malaysia, Indonesia and Vietnam.

If we’ve learned one thing from the Snowden revelations, it’s that what can be spied on will be spied on. Since the advent of what used to be known as the World Wide Web, it has been a relatively simple matter for network attackers—whether it’s the NSA, Chinese intelligence, your employer, your university, abusive partners, or teenage hackers on the same public WiFi as you—to spy on almost everything you do online. HTTPS, the technology that encrypts traffic between browsers and websites, fixes this problem—anyone listening in on that stream of data between you and, say, your Gmail window or bank’s web site would get nothing but useless random characters—but is woefully under-used. The ambitious new non-profit Let’s Encrypt aims to make the process of deploying HTTPS not only fast, simple, and free, but completely automatic. If it succeeds, the project will render vast regions of the internet invisible to prying eyes.

Encryption also prevents attackers from tampering with or impersonating legitimate websites. For example, the Chinese government censors specific pages on Wikipedia, the FBI impersonated The Seattle Times to get a suspect to click on a malicious link, and Verizon and AT&T injected tracking tokens into mobile traffic without user consent. HTTPS goes a long way in preventing these sorts of attacks. And of course there’s the NSA, which relies on the limited adoption of HTTPS to continue to spy on the entire internet with impunity. If companies want to do one thing to meaningfully protect their customers from surveillance, it should be enabling encryption on their websites by default.

Let’s Encrypt, which was announced this week but won’t be ready to use until the second quarter of 2015, describes itself as “a free, automated, and open certificate authority (CA), run for the public’s benefit.” It’s the product of years of work from engineers at Mozilla, Cisco, Akamai, Electronic Frontier Foundation, IdenTrust, and researchers at the University of Michigan. (Disclosure: I used to work for the Electronic Frontier Foundation, and I was aware of Let’s Encrypt while it was being developed.) If Let’s Encrypt works as advertised, deploying HTTPS correctly and using all of the best practices will be one of the simplest parts of running a website. All it will take is running a command. Currently, HTTPS requires jumping through a variety of complicated hoops that certificate authorities insist on in order prove ownership of domain names. Let’s Encrypt automates this task in seconds, without requiring any human intervention, and at no cost.

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.
