A novel construction of substitution box for image encryption applications with Gingerbreadman chaotic map and S 8 permutation

Zeeshan Asghar, Majid Khan

Abstract

In this communication, we present a technique to synthesize resilient nonlinear mechanisms for the construction of substitution box. The proposed nonlinear component assists in transforming the intelligible message or plaintext into an enciphered format by the use of Gingerbreadman chaotic map and S8 permutations. The proposed substitution box is sensitive to the initial conditions provided to the chaotic system, which are subsequently used as parameters in creating an instance. The simulation results show that the use of the proposed substitution box to image encryption scheme provides an efficient and secure way for real-time communications.
