| Abstract | At the beginning of the paper we give an overview of linear and differential cryptanalysis of block ciphers. We describe two extensions of linear cryptanalysis (analysis with multiple expressions [7] and differentiallinear cryptanalysis [10]) which form the basis of the conducted experiments. Then we describe the functioning of truncated differentials [1],[8] and the usage of differential structures ([1],[2] and [3]). In the second part of the article we present experimental results of implementation of differential-linear cryptanalysis with multiple expressions applied to reduced DES variants. In an attack on DES reduced to 8 rounds we obtained a significant reduction in the number of needed chosen pairs of texts – reduction by a factor greater than 4. |
