Моделювання криптографічних перетворень зображень на основі їх матрично-бітовозрізової декомпозиції та матричних моделей перестановок з верифікацією цілісності

Abstract

Designed matrix models of permutations for cryptographic transformations of images are proposed and in Mathcad programmed, monitored and evaluated. In the work are given results of modeling of matrix models of cryptographic transformations of images with matrix bit-plane decomposition and mixing. The simulating results for images with 128 * 128 and 512 * 512 pixels are shown. The developed matrix models of permutations based on matrix bit-plane decomposition for images cryptographic transformations are shown, that they have high entropic quality criteria, high performance for direct and inverse transformations.
