Serpent is a 32-round AES block cipher finalist. In this paper we present several attacks on reduced-round variants of Serpent that require less work than exhaustive search. We at...
Abstract. In this paper we combine a recent rotational cryptanalysis with the rebound attack, which results in the best cryptanalysis of Skein, a candidate for the SHA-3 competitio...
