New AES Attack Documented 236

avxo writes "Bruce Schneier covers a new cryptanalytic related-key attack on AES that is better than brute force with a complexity of 2^119. According to an e-mail by the authors: 'We also expect that a careful analysis may reduce the complexities. As a preliminary result, we think that the complexity of the attack on AES-256 can be lowered from 2^119 to about 2^110.5 data and time. We believe that these results may shed a new light on the design of the key-schedules of block ciphers, but they pose no immediate threat for the real world applications that use AES.'"
