Abstract Impossible Differential Cryptanalysis (IDC)[4] uses impossible differential
characteristics to retrieve a subkey material for the first or the last several rounds of block …

The general strategy of impossible differential cryptanalysis is to first find impossible
differentials and then exploit them for retrieving subkey material from the outer rounds of …

In this paper, we propose a systematic method for finding impossible differentials for block
cipher structures, which we call the unified impossible differential finding method or UID …

As two important cryptanalytic methods, impossible differential and integral cryptanalysis
have attracted much attention in recent years. Although relations among other cryptanalytic …

Impossible differential cryptanalysis is a very popular tool for analysing the security of
modern block ciphers and the core of such attack is based on the existence of impossible …

This paper studies the security of the block ciphers ARIA and Camellia against impossible
differential cryptanalysis. Our work improves the best impossible differential cryptanalysis of …

Impossible differential cryptanalysis is a powerful technique to recover the secret key of
block ciphers by exploiting the fact that in block ciphers specific input and output differences …

Estimating immunity against differential and linear cryptanalysis is essential in designing
secure block ciphers. A practical measure to achieve it is to find the minimal number of …

This paper introduces a practical algorithm for deriving the best differential characteristic and
the best linear expression of DES. Its principle is based on a duality between differential …

The differential attack is a basic cryptanalytic technique for block ciphers. Application of
machine learning shows promising results for the differential cryptanalysis. In this paper, we …
