Abstract

This article proposes an algorithm of confusion and diffusion of image encryption based on the logistic map and the attractor of Henon-Lozi. We chose the initial parameters of the logistic map and the Henon-Lozi Attractor as secret keys. The Henon-Lozi Attractor is used to generate a chaotic matrix to mask the pixel values and the logistic map uses to generate random sequences to make a permutation between the pixels. The computer experience such as statistical analysis, sensitivity analysis proves that the proposed image encryption algorithm is robust and secure enough to be used in practice.
