An efficient and secure cipher scheme for images confidentiality preservation

A novel image encryption scheme base d on two rounds of substitution –diffusion is proposed. Two main objectives have guided the design of this scheme:(a) robustness against the most known type of attack s (statistical, chosen /known plain-text, cipher text-only and brute force attack s) and (b) efficiency in terms of computational complexity ( i.e., execution time reduction) in order to meet recent mobiles ’ applications ’requirements. First, a dynamic key, changed for every input image is generated and used as the basis to construct the substitution an d diffusion processes. Then, the encryption process is performed by the transmitter based on a non-linear S-box (substitution ) and a matrix multiplication (difusion), applied on each sub-matrix of the image. At the desti-nation side, decryption is applied in the reverse order. We have conducted several series of experiments to evaluate the effectiveness of the proposed scheme. The obtained results validated the robustness of our scheme against all considered type s of attack s and showed an improvement in terms of execution time reduction compared to the recent existed image-encryption schemes
