Based on the combined differential method, the accelerating technique of cryptanalysis on SAFER-64 systems is investigated in this paper. The technique of plexertext pair selection, the algorithms of reducing the range of the byte keys, and the elimination of incorrect keys are presented . It is shown that the attacking on SAFER-64 systems is accelerated highly with these techniques through theoretical analysis and digital tests.
