The code-cracking history of World War II, and in particular the Enigma Machine story, are legendary. But a feat of equal or even greater cryptographic virtuosity has been overshadowed by that well-known tale.
Naturally, that's of interest to the hackers and tinkerers at this year's Chaos Communication Camp. Sven Moritz Hallberg reconstructed the events today for the campers here.
MIT Professor Ronald L. Rivest, who helped develop one of the world's most widely used Internet security systems, has been named the 2007 Marconi Fellow and prize-winner for his pioneering work in the field of cryptography, computer and network security.
Rivest, the Andrew and Erna Viterbi Professor in MIT's Department of Electrical Engineering and Computer Science, will receive the award and accompanying $100,000 prize at the annual Marconi Society Award Dinner on Sept. 28 at the Menlo Circus Club in Atherton, Calif.
In the computer printer business, everyone knows the big money comes from the sale of ink cartridges.
Most of these cartridges are made by printer manufacturers and sell for a substantial premium. Some come from unauthorized sources, sell for substantially less and attract the attention of antipiracy lawyers.
The strength of the encryption now used to protect banking and e-commerce transactions on many websites may not be effective in as few as five years, a cryptography expert has warned after completing a new distributed-computing project.
Arjen Lenstra, a cryptology professor at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, says the distributed computation project, conducted over 11 months, achieved the equivalent in difficulty of cracking a 700-bit RSA encryption key, so it doesn’t mean transactions are at risk — yet.
The ongoing war between content producers and hackers over the AACS copy protection used in HD DVD and Blu-ray discs produced yet another skirmish last week, and as has been the case as of late, the hackers came out on top. The hacker "BtCB" posted the new decryption key for AACS on the Freedom to Tinker web site, just one day after the AACS Licensing Authority (AACS LA) issued the key.
