A Method for Designing Dynamical S-Bozes Based on Discrete Chaos Map System
This paper presents aaaa method for obtaining dynamically cryptographically strong substitution boxes (S- Sboxes) boxes) based on discrete chaos map system (DCMS) 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 aaaa result, our approach is suitable for practical application in designing block cryptosystem.
