Construction of Dynamical Non-linear Components Based on Lorenz System and Symmetric Group of Permutations

摘要: This paper is devoted to presenting a new technique for generating S-boxes based on Lorenz system and S8 group of permutations. Within the algorithm, initial condition employed drive hyperchaotic generate chaotic sequence which used construct S-boxes. With different conditions, many distinct can be obtained dynamically. Some cryptographic properties good S-box such as bijection, nonlinearity, SAC, BIC differential approximation probability are found hold in from proposed method. The analytic results indicate that all criteria designing robust achieved. comparison method with other chaos-based schemes indicates our have better performance respect some properties. Classification information security techniques its applications
