英文摘要Serpent is one of the five AES finalist. In 2001, Biham, Dunkelman and Keller present a differential cryptanalysis of Serpent up to 8 rounds with 256-key bits by using 214 6-round differential characteristics with probability 2-93. In this paper we present a new 6-round differential characteristic ΩA with the same probability 2-93. By changing the input differences of ΩA, we get a characteristic ΩB with probability 2-95. We give an improved differential attack on 8-round Serpent with 256-bit keys by using 219.62 6-round characteristics with probability 2-95. Similarly, we present an improved differential attack on 8-round Serpent with 256-bit keys by using 225.24 6-round characteristics with probability 2-97. © 2010 IEEE.
