title = "Impossible differential cryptanalysis of zodiac",
abstract = "We discuss the impossible differential cryptanalysis of the blockcipher Zodiac [7]. The main design principles of Zodiac are simplicity and efficiency. However the diffusion layer in its round function is too simple to offer enough security. An impossible differential cryptanalysis is a proper method to attackthe weakness of Zodiac. Our attack using two 14-round impossible characteristics derives 128-bit master key of the full 16-round Zodiac with its complexity 2119 encryption times faster than the exhaustive search. The efficiency of the attackcompared with exhaustive search increases as the key size increases.",
