Synergistic Construction of High-Performance S-Boxes based on Chaotic Systems: A Paradigm Shift in Cryptographic Security Design

Exchange of information between two nodes is a big issue in intenet these days. Multiple cryptosystems employed for this porpose with various mathmatical approaches. Most of these approaches uitilize subsitutions and pemutations. The subsituation S-box is a look up table that exchange x bits input with y bits output is incharge of substitution approach. The build of S-box with stong cryptographic power is important in recent cryptosystems. In this paper a novel approach for building roboust and dynamic S-box with compound multi-dimentional chaotic systems. Lorenze and henon maps employed for construction of strong S-Box with multiple security performance metrics :non-linearity(NL), Strict Avalanche Criterion (SAC), Bit-Independence Criterion (BIC), Linear-Probability (LP) and differential-Probability (LP).The results showed that proposed S_box is will be powerfull for modern cryptosystems.
