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. We introduce a new cryptanalytic technique based on Wagner's boomerang and inside-out attacks. We first describe this new attack in terms of the original boomerang a...
Abstract. This paper reports on the improved and multiple linear cryptanalysis of reduced round Serpent by mean of a branch-and-bound characteristic search within the algorithm. We...
Abstract. In this paper, we present a new technique for Matsui's algorithm 2 using multidimensional linear approximation. We show that the data complexity of the attack can be...
We proposed a new block cipher, Serpent, as a candidate for the Advanced Encryption Standard. This algorithm uses a new structure that simultaneously allows a more rapid avalanche,...
