摘要: This paper reports impossible-differential (ID) attacks on reduced-round versions of the Rijndael cipher with text blocks larger than 128 bits. These follow framework by Biham-Keller and Cheon et al. AES, reach up to seven rounds large-block variants. Even though these ciphers are not standardized as FIPS, like it is important evaluate security other since they provide internal states when used primitives for construction stream hash functions. The main contributions this longer ID distinguishers found versions, compared ones AES.
