Abstract(in English) | The block cipher GOST was proposed in former Soviet Union in 1989. In this paper we present differential cryptanalysis of reduced rounds of GOST. Introducing the idea of using a set of differential characteristics, which is a partitioning type, we can reduce the influence of the key value upon the probability as well as get high differential probability. Using 2^<51> chosen plaintexts the key of 13-rounds of GOST can be obtained. Next we expand the analysis with combining related-key attack. Using 2^<56> chosen plaintexts the key of 21-rounds of GOST can be obtained. |
