A novel and secure plaintext-related image encryption scheme is given in this paper using hyper-chaotic Lorenz system and hash function. In our scheme, we used the classical encryption architecture: permutation and diffusion. The initial conditions of hyper-chaotic Lorenz system which is employed in permutation and key stream generation algorithms are generated by information of the original image and initial key. Therefore, the encryption process has a strong relationship with plain image in the proposed scheme. So, our work performs excellently on resisting the known-plaintext attack. In addition, results of many widely used security analyses and comparisons with other works show that our work has outstanding security performance for the digital image communication.
