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. During diffusion, the avalanche effect is achieved with 2-D Pseudo Hadmard transforms followed by diffusion in two directions (forward and backward) with multiple additions and xor operations. This stage ensures resistance against differential attacks. The security and performance of the proposed method is analyzed thoroughly by using key-sensitivity, key-space, statistical, entropy, differential and performance analysis. The proposed scheme achieves the required level of security with only one round of encryption operation. Hence the proposed method is computationally fast.
