Improvements for Finding Impossible Differentials of Block Cipher Structures

2017/12/19
In this paper we improve Wu and Wang's method for finding impossible differentials of block cipher structures. This improvement is more general than Wu and Wang's method that it can find more impossib...
New Automatic Search Tool for Impossible Differentials and Zero-Correlation Linear Approximations

2016/7/13
Impossible differential cryptanalysis and zero-correlation linear cryptanalysis are two of the most useful cryptanalysis methods in the field of symmetric ciphers. Until now, there are several automat...
Cryptanalysis of Block Ciphers Using Almost-Impossible Differentials
Block Cipher Cryptanalysis Almost-Impossible Differential Crypton
2010/9/21
In this paper, inspired from the notion of impossible differentials, we present a model to use differentials that are less probable than a random permutation. We introduce such a distinguisher for 2 r...
