An Algebraic Approach of Multilayer Color Image Cryptosystems via Permutation-Substitution Groups and Chaotic Maps

In this manuscript, an algebra-based image encryption scheme is presented, in which the application of an S-box derived from quadratic polynomial mappings over the ring ℤ256, chaotic maps, and an algebraically enriched random matrix affine cipher is included. The algebraic founda...
