Abstract— GOST 28147-89 is a well-known block cipher and the official encryption standard of the Russian Federation since 1990s. This algorithm has been approved to be capable of against the differential cryptanalysis. In this paper, we prove theorically property for key mixing with the addition modulo 232 in the view of differential cryptanalysis. Then, we construct a tool-box to search either the best differential characteristic for round-reduced GOST 28147-89 or good differential characteristics for full GOST 28147-89.
