Recently, several chaotic based image encryption schemes have been proposed, each of them has its own strengths and limitations more or less in terms of security level and computational speed. In this paper, a novel approach for image encryption based on a 2-D Zaslavskii map and Pseudo Hadmard transform is proposed. The encryption process is composed of two stages, i.e. permutation and diffusion. The permutation is achieved by scrambling rows and columns using chaotic values. This stage substantially reduces the correlation between neighboring pixels.
