It takes only a second to crack the handful of weak keys. Are there more out there? Cryptographic keys generated with older software now owned by technology company Rambus are weak enough to be broken instantly using commodity hardware, a researcher reported on Monday. This revelation is part of an investigation that also uncovered a handful of weak keys in the wild. "The problem is that both primes are too similar," Böck said in an interview. "So the difference between the two primes is really small."

“What he showed in the presentation is very unlikely to be anything like a proof of the Riemann hypothesis as we know it,” says Jørgen Veisdal, an economist at the Norwegian University of Science and Technology in Trondheim who has previously studied the Riemann hypothesis. “It is simply too vague and unspecific.” Veisdal added that he would need to examine the written proof more closely to make a definitive judgement. The Riemann hypothesis, one of the last great unsolved problems in math, was first proposed in 1859 by German mathematician Bernhard Riemann. It is a supposition about prime numbers, such...

It lights you up like a Vegas casino, says compsci boffin Usenix Enigma Although the cops and Feds wont stop banging on and on about encryption - the spies have a different take on the use of crypto. To be brutally blunt, they love it. Why? Because using detectable encryption technology like PGP, Tor, VPNs and so on, lights you up on the intelligence agencies' dashboards. Agents and analysts don't even have to see the contents of the communications - the metadata is enough for g-men to start making your life difficult. "To be honest, the spooks love PGP," Nicholas...
