Well the reasons that he states look sound. How many other cipher approved for classified data have been cryptanalysed?

- brohee 12y agoDES, never approved for classified data. The biclique attack on AES looks a lot more impractical than the results on GOST... Looks like O(2^124) time complexity and a stupendous amount of data if I scanned the paper properly....
- tptacek 12y agoBillet attacks a white-box construction, not AES itself. White box cryptography involves allowing the attacker access to both the algorithm and the key; you can think of it as a mathematical abstraction of a tamper-proof smartcard. It's not a cryptanalysis of AES.
