A good comparison between AES & Serpent is at http://www.scribd.com/doc/4522/Comparison-between-AESRijndael-and-Serpent I'm using Serpent myself. With modern hardware the speed penalty of that cipher is not the bottleneck of overall performance anymore. Possibly the most cited criticism of AES is its simple algebraic structure, mentioned in "Practical Cryptography", 2003, pp56-57. Anyway, the good news is that none of the major AES finalists have been broken (as we know of; it cannot hurt to be paranoid about the matter), twofish, AES, Serpent. -- left blank, right bald
