Research on Algorithm of Generating S-box Based on Uniform Chaotic System

A new quadratic polynomial chaotic system is given and homogenized based on its probability density function. Then, based on the chaotic systems before and after homogenization, an S-box generation algorithm is constructed. By numerical simulation, the algorithm dynamically generates 300 S-boxes and then analyses their Differential Probability (DP) and Linear Probability (LP). The statistical results show that the uniform chaotic system can produce better performance of S-boxes.
