Designing S-box Using Tent-Sine Chaotic System While Combining the Traits of Tent and Sine Map

Secure exchange of sensitive information between different entities is a serious challenge in today’s environment. Therefore, various cryptosystems have been created specifically for this purpose. Various operations are used these cryptosystems. The most common substitution and permutation. substitution-box (S-box), look-up table that takes x bits as input replaces them with y bits, responsible the operation. construction an S-box strong cryptographic attributes essential part building robust secure cryptosystem.Numerous researchers dedicated their efforts to devising intricate techniques constructing S-boxes. In study, novel approach proposed design dynamic based on compound-chaotic map. suggested method characterized by its simplicity resilience. Notably, Tent-Sine chaotic system significantly expands range, setting it apart from other systems rendering more suitable applications. This research introduces promising avenue enhancing security effectiveness S-boxes, contributing advancement systems. A number widely accepted metrics, such Non-Linearity (NL), Strict Avalanche Criterion (SAC), Bit Independence (BIC), Linear Probability (LP), Differential (DP), extensively exercised analysis evaluation S-Box’s strength. results compared S-boxes researchers, observed cryptographically sound worthy inclusion modern
