Description
Summary:Several proposals of chaos-based algorithms have been proposed for secure communication and image encryption. In this paper, a new algorithm for colour image encryption has been proposed. The algorithm is based on a new 3-dimensional (3-D) discrete time chaos system which performs the diffusion and confusion processes. The novelty of the proposed work is the new 3-D map defined by five nonlinear terms and three control parameters to ensure better chaotic properties. Moreover, the proposed new map is used to perform 3-stage encryption algorithm which achieves better performance while preserving the traditional confusion-diffusion structure. Security analysis of the proposed algorithm is investigated and compared to some existing methods in terms of key space, metric entropy and correlation. Simulated results of our encryption algorithm prove its performance and suitability for colour image encryption.
