Abstract
In this article, we have presented a procedure to produce resilient nonlinear mechanisms used for the construction of substitution box (S-box). The planned nonlinear component assists in transforming the intelligible message or plaintext into an enciphered format by the use of Zaslavskii chaotic map and S-8 permutations. A substitution box is generated that uses initial conditions, apply particular chaotic parameter values. The results of proposed S-box are compared with already existing S-boxes.
