If your cryptography predates The Fresh Prince, you need better cryptography. With recognition of the need for secure communication standards finally going mainstream, crypto researcher and Johns Hopkins University professor Matthew Green takes a hard look at the de facto standard everyone is jumping on, and suggests that we can and should do a lot better.

"Undisclosed until now was that RSA received $10 million in a deal that set the NSA formula as the preferred, or default, method for number generation in the BSafe software, according to two sources familiar with the contract. Although that sum might seem paltry, it represented more than a third of the revenue that the relevant division at RSA had taken in during the entire previous year, securities filings show." Previous
On January 5th 2012, an image was uploaded to various image boards. It contained two messages. One was obvious & easy to read. In white letters on a black background it said:
Hello. We are looking for highly intelligent individuals. To find them, we have devised a test. There is a message hidden in this image. Find it, and it will lead you on the road to finding us. We look forward to meeting the few that will make it all the way through. Good luck. 3301As promised there was another message hidden inside the image. It was the start of a bizarre, as yet unexplained chain of complex hidden messages leading those who could solve them on a journey across the Internet and around the world towards a destination none of them could predict with certainty. Is it a highly evolved ARG? Is it a recruitment campaign for the NSA? Welcome to the mystery of Cicada 3301.

In a crackdown that FBI claims to be about hunting down pedophiles, half of the onion sites in the TOR network has been compromised, including the e-mail counterpart of TOR deep web, TORmail. FreedomWeb, an Irish company known for providing hosting for Tor "hidden services" -- services reached over the Tor anonymized/encrypted network -- has shut down after its owner, Eric Eoin Marques, was arrested over allegations that he had facilitated the spread of child pornography.

Enigma breaker Alan Turing will be posthumously pardoned. Turing helped the Allies win WWII by developing the methods that broke the German Enigma code -- which didn't stop Britain from convicting him of gross indecency under anti-homosexuality legislation in 1951 and subjecting him to chemical castration. Two years later, he committed suicide by swallowing cianide. The British government has now "signalled that it is prepared to support a backbench bill that would pardon Turing."

An advanced and well-orchestrated computer spy operation that targeted diplomats, governments and research institutions for at least five years has been uncovered by security researchers in Russia.
The highly targeted campaign, which focuses primarily on victims in Eastern Europe and Central Asia based on existing data, is still live, harvesting documents and data from computers, smartphones and removable storage devices, such as USB sticks, according to Kaspersky Lab, the Moscow-based antivirus firm that uncovered the campaign. Kaspersky has dubbed the operation “Red October.”[more inside]

Bitcoin is growing up: early adopters lost money due to bad backups; the US Senate wants to crack down due to possible illegal drug purchases with the digital coins; it had its Black Friday, losing 30% of its value in one day (after a 5,600% increase in the first year); the Economist weighs in; and now an alledged heist of 25k bitcoins (original forum post), valued between $250k and $750k on the Mt. Gox exchange. Currently 154 petaflops of CPU and GPUs are computing SHA256 hashes in tight loops, easily beating the #1 on the top500, the Tiahne-1A with 2.56 petaflops.

Bitcoin is a peer-to-peer digital currency. Trading at eight dollars this week—and being used to pay for everything from freelance programming jobs to magic mushrooms—it has been described as “the most dangerous open-source project ever created” and “an unambiguous challenge to the government monopoly on the power to print money.” Estimated at over 20 petaFLOPS the Bitcoin network is currently the fastest virtual supercomputer in the world.

On June 30, 1999, sheriff’s officers in St. Louis, Missouri discovered the body of 41-year-old Ricky McCormick. He had been murdered and dumped in a field. The only clues regarding the homicide were two encrypted notes found in the victim’s pants pockets. The FBI is now asking the public to help them solve the murder.
How To Make Anything Signify Anything "By the time he retired from the National Security Agency in 1955, Friedman had served for more than thirty years as his government’s chief cryptographer, and—as leader of the team that broke the Japanese PURPLE code in World War II, co-inventor of the US Army’s best cipher machine, author of the papers that gave the field its mathematical foundations, and coiner of the very term cryptanalysis—he had arguably become the most important code-breaker in modern history."
"Few false ideas have more firmly gripped the minds of so many intelligent men than the one that, if they just tried, they could invent a cipher that no one could break."
The CIA is watching him. He's been addressed directly by powerful people all across the United States government. And earlier today on his website and across the internet, the same man has placed a 1.4 gigabyte encrypted file labeled "insurance."

Thomas Jefferson's cipher message from Robert Patterson For more than 200 years, buried deep within Thomas Jefferson's correspondence and papers, there lay a mysterious cipher -- a coded message that appears to have remained unsolved. Until now.... To Mr. Patterson's view, a perfect code had four properties: It should be adaptable to all languages; it should be simple to learn and memorize; it should be easy to write and to read; and most important of all, "it should be absolutely inscrutable to all unacquainted with the particular key or secret for decyphering."

This is an ironic tale of the consequences of inept application of cryptographic tools. Or is it? Dan Egerstad, a Swedish hacker, gained access to hundreds of computer network accounts around the world, belonging to various embassies, corporations and other organizations. How did he do it? Very easily: by sniffing exit traffic on his Tor nodes. [more inside]
If you work at Langley and you need a break from actual intelligence gathering, you can always try to crack the code to the sculpture right outside the cafeteria window. Kryptos is a sculpture by James Sanborn located on the CIA grounds which contains a four-part coded message: sections 1-3 have been solved (with Sanborn admitting he made a typo in section 2). Perhaps you'd like to join Elonka (and the hive mind) in having a go at section 4.

The Reader of Gentlemen's Mail In the spring of 1919, when the father of American cryptography, Herbert O. Yardley, drew up a plan for a permanent State Department codebreaking organization — a "black chamber — he estimated that a modest $100,000 a year would buy a chief (Yardley) and fifty clerks and cryptanalysts. Yardley rented a three-story building in New York City: on East 38th Street just off Fifth Avenue, he put two dozen people to work under civilian cover—as the Code Compiling Company. His summary dismissal happened in 1929 at the hand of incoming Secretary of State Henry Stimson, who closed down the Cipher Bureau with the casual observation that "gentlemen do not read each other's mail". The son of a railroad telegrapher, a man with a lively Jazz Age interest in money, good-looking women, and drinks at five, Yardley not only taught his country how to read other people's mail but wrote two of the enduring American books—the memoir The American Black Chamber (1931), and The Education of a Poker Player (1957).
Learn to Safecrack! [pdf] Last year, computer scientist and cryptologist Matt Blaze drew ire from the locksmithing community for publically revealing information on how to create the master key to a lock (previous MetaFilter discussion). He's back with a paper on cracking safes. Once again, locksmiths are up in arms over Blaze's disregard of trade secrets. Apparently, safes adhere to the principle of security through obscurity rather than Kerckhoff's Law. [via]
Rongorongo! Say it twice -- don't it feel nice? Most people think of the enigmatic maoi when they think of Easter Island but an equally vexing mystery is found in twenty-six wooden objects which contain pictographic symbols comprising...what? A language? A mnemomic system for recording stories now long forgotten? A resource for modern primitives' tribal tatoos? We could ask, but the authors are long-gone -- the victims of hard times -- leaving only a few tablets and a bunch of carved stone to puzzle over.

There comes a time when people at a technical conference like this need something more relaxing. A change of pace. A shift of style. To put aside all that work stuff and think of something refreshingly different. So let's talk about coding theory.
You've probably heard of the WWII Navajo "code talkers" who managed to baffle crack Japanese cryptanalysts and were credited with enabling US success at Iwo Jima. Civil engineer, journalist and photographer Philip Johnston was the determined mind behind the "windtalkers". The son of missionaries, Johnston grew up on a Navajo reservation and was one of only a handful of outsiders fluent in the Navajo language. A bit of his background is included this article, and you can read a complete history of his plan, view an archive of photos by Johnston, and see copies of his enlistment application letter to the Marine Corps commandant, as well as a recommendation letter from the Commanding General.
