Abstract. In this paper, we discuss ways to attack various reducedround variants of MARS. We consider cryptanalysis of two reducedround variants of MARS: MARS with the full mixing ...
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...
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...
