Dans cet article, nous discutons de l’impossible cryptanalyse différentielle pour le chiffrement par blocs Zodiac. Les principaux principes de conception de Zodiac incluent la simplicité et l’efficacité. Cependant, la couche de diffusion dans sa fonction ronde est trop simple pour offrir une sécurité suffisante. L'impossible cryptanalyse différentielle exploite cette faiblesse de Zodiac. Notre attaque utilisant une caractéristique impossible de 14 tours dérive le passe-partout de 128 bits du Zodiac complet de 16 tours plus rapidement que la recherche exhaustive. L'efficacité de l'attaque par rapport à la recherche exhaustive augmente à mesure que la taille de la clé augmente.

Abstract: In this paper, we discuss the impossible differential cryptanalysis for the block cipher Zodiac. The main design principles of Zodiac include simplicity and efficiency. However, the diffusion layer in its round function is too simple to offer enough security. The impossible differential cryptanalysis exploits such weakness in Zodiac. Our attack using a 14-round impossible characteristic derives the 128-bit master key of the full 16-round Zodiac faster than the exhaustive search. The efficiency of the attack compared with exhaustive search increases as the key size increases.
