Simulating and research of block parametric matrix affine-permutation ciphers (BP_MAPCs) for cryptographic transformations

Abstract

New block parametric matrix-algebraic models and matrix affine-permutation ciphers for CTs are proposed and modulated. The results of their modeling are presented using direct and inverse CT scans over images as an example, which indicates their correct operation and effectiveness. The entropy-histogram analysis of the obtained cryptograms, the advantages of the proposed modifications of ciphers with an increased permutation matrix are shown. The aspects of creating existing MKs are considered. Models can be implemented on matrix processors and have high speed, stability of transformations, and are more resistant to attacks.
