A scheme based on algebraic and chaotic structures for the construction of substitution box

The use of nonlinear (chaotic) transformations in cryptography to generate confusion in the course of encryption procedure is the recent trend. In this article, a novel chaotic system is presented based on the existing chaotic maps. A proficient cryptosystem technique is proposed for constructing substitution box using this novel 1D chaotic structure. The key based dynamical feature of the chaotic system to synthesize strong substitution boxes is the main advantage of the suggested scheme. Then, the constructed component of the block cipher is evaluated using statistical and algebraic analyses. The outcomes of theses analyses certify that the proposed cryptosystem has great potential and superior performance for noticeable dominance in various cryptographic applications in comparison with the existing procedures.
