WebThis work aims at determining when the two-round maximum expected differential probability in an SPN with an MDS diffusion layer is achieved by a differential having the fewest possible active Sboxes. This question arises from the fact that minimum-weight differentials include the best differentials for the AES and several variants. WebAbstract. In this paper we study the probability of differentials and characteristics over 2 rounds of the AES with the objective to understand how the components of the AES round transformation interact in this respect. We extend and correct the analysis of the differential properties of the multiplicative inverse in GF (2 n) given in [9].

WebProving bounds on the expected differential probability (EDP) of a characteristic over all keys has been a popular technique of arguing security for both block ciphers and hash functions. In fact, to a large extent, it was the clear formulation and elegant deployment of this very principle that helped Rijndael win the AES competition. WebFeb 3, 2024 · In this paper, first, we design a more efficient MILP-based differential search model. Using this model, we give a 12-round differential characteristic with probability 2^ {-60} and get the first 19-round key-recovery attack on GIFT-64. Second, we improve our MILP-based model for block ciphers with large state size.
