How to Get Next-Level Cryptography With a Crappy Old Nokia Phone

Remember the Nokia N9? Probably not—but geek points if you do—because it was a smartphone that was DOA and used by pretty much no one. But even a three-year-old smartphone is pretty sophisticated piece of machinery. Using just an N9 and light, physicists have found a way to generate the random numbers algorithms used… » 9/12/14 3:57pm 9/12/14 3:57pm

It was a beacon among amateur wireless enthusiasts around the United… » 7/11/14 3:43pm 7/11/14 3:43pm

The NSA Hated Civilian Encrypted Data Way Back in the 1970s

In the 1970s, civilian researchers at places like IBM, Stanford and MIT were developing encryption to ensure that digital data sent between businesses, academics and private citizens couldn't be intercepted and understood by a third party. This concerned folks in the U.S. intelligence community who didn't want to get… » 7/24/13 3:01pm 7/24/13 3:01pm

Turing's Nazi Enigma Code-Breaking Secrets Have Been Declassified

Over 70 years ago, father of computer science Alan Turing developed the techniques which enabled quick and efficient decryption of the Nazis' Enigma-scrambled messages. Now, the secrets behind his techniques—hidden away in research documents since the Second World War—have been declassified. » 4/23/12 7:40am 4/23/12 7:40am

Quantum Encryption Network Goes Live, Claims To Be Unbreakable

Scientists have connected up the world's first computer network protected by “quantum cryptography,” a supposedly unbreakable system that functions off a scheme based on the Heisenberg Uncertainty Principle. For us non-science folk, that means that you can't grab information transmitted through the network without… » 10/09/08 11:00pm 10/09/08 11:00pm
