MULTIMEDIA TOOLS AND APPLICATIONS(2022)
Abstract
In this paper, highly nonlinear substitution boxes (S-boxes) are generated by utilizing a chaotic map accompanied by the Grey wolf optimization technique. To check their applicability in the encryption scheme, an encryption scheme utilizing a three dimensional (3D) logistic map and the proposed S-boxes for confusion is proposed. The performance analyses of suggested S-boxes are performed and compared with existing techniques. Moreover, security analysis of projected encryption scheme is also performed and tabulated. The results show the strength of the proposed S-boxes in the design of encryption schemes.
