A novel design of Chaos based S-Boxes using genetic algorithm techniques

In this manuscript we present a novel method to design strong substitution Boxes based on chaos function and genetic algorithm techniques. Furthermore, we analyse the strength of the proposed S-Boxes. The proposed methodology is analyzed and tested for the following criteria: bijective property, nonlinearity, strict avalanche criterion, output bits independence criterion and equiprobable input/output XOR distribution. Numerical simulation and security analysis demonstrate that the scheme is practical in image encryption.
