摘要: In this paper, a scheme for the construction of substitution boxes (S-boxes) based on chaotic map and S8 (symmetric group permutation) is presented. The properties such as nonlinearity, strict avalanche resistance against differential cryptanalysis are analyzed in detail. result shows that criterion designing good S-box can be met approximately. As result, our approach suitable practical application block cryptosystem.
