Abstract
This paper presents a method for obtaining dynamically cryptographically strong substitution boxes (Sboxes) based on discrete chaos map system (DCMS). The cryptographical properties such as bijection, nonlinearity, strict avalanche, output bits independence and equiprobable input/output XOR distribution of these S-boxes are analyzed in detail. The results of numerical analysis show that all the criteria for designing good S-box can be satisfied approximately. As a result, our approach is suitable for practical application in designing block cryptosystem.
