Multiple-of Property for Related-Differential Distinguishers on 5-Round AES (opens in new tab)

A key-independent secret-key distinguisher identifies inherent structural deviations of a block cipher from an ideal random permutation without recovering any information about the secret key. For the Advanced Encryption Standard (AES), various key-independent secret-key distinguishers have been proposed on reduced-round versions. In this paper, we study related-differential distinguishers for 5-round AES that combine a 1-round related differential trail with the 4-round generalized zero-diff...
