The Rectangle Attack - Rectangling the Serpent

Download www.iacr.org

Abstract. Serpent is one of the 5 AES ﬁnalists. The best attack published so far analyzes up to 9 rounds. In this paper we present attacks on 7-round, 8-round, and 10-round variants of Serpent. We attack a 7round variant with all key lengths, and 8- and 10-round variants with 256-bit keys. The 10-round attack on the 256-bit keys variants is the best published attack on the cipher. The attack enhances the ampliﬁed boomerang attack and uses better diﬀerentials. We also present the best 3-round, 4-round, 5-round and 6-round diﬀerential characteristics of Serpent.
