| Abstract: | This paper points out the contradiction between the way of computing the differential characteristic probability and the principle of differential cryptanalysis, gives a deep reaserch on it and proposes a equivalent sufficient condition. The goal of the work is trying to solve the problem of the basic theoretic foundation for differential cryptanalysis. |
