摘要：This paper presented a method for obtaining cryptographically strong substitution box (S-box) based on piecewise linear chaotic map (PWLCM). The cryptographical properties were analyzed, such as bijection, nonlinearity, strict avalanche, output bits independence and equiprobable input/output XOR distribution. The results of numerical analysis show that all the criteria for designing good S-box can be satisfied approximately and the proposed cryptosystem is a highly reliable system suitable for secure network communication. ?
