Another New AES Attack

Bruce Schneier gives us an update on some ongoing cryptanalysis of AES
- http://www.schneier.com/blog/archives/2009/07/another_new_aes.html.

According to his blog entry, "This new attack, by Alex Biryukov, Orr
Dunkelman, Nathan Keller, Dmitry Khovratovich, and Adi Shamir, is much
more devastating. It is a completely practical attack against
ten-round AES-256."

While ten-round AES-256 is not actually used anywhere, Schneier goes
on to explain why this shakes some of the cryptology community's
assumptions about the security margins of AES.
