Abstract :
In this paper, a method for obtaining substitution boxes (S-boxes) dynamically based on chaotic map is presented. The properties such as nonlinearity, strict avalanche and resistance against the differential cryptanalysis are analyzed in detail. The result shows that the criterion for designing good S-box can be met approximately. As a result, our approach is suitable for practical application in designing block cryptosystem.
