Summary:
In recent years, various image encryption schemes based on the permutation-diffusion architecture have been proposed. Under this architecture, the pixel positions are firstly shuffled by one map in the permutation stage, and then the pixel values are modified sequentially by another map in the diffusion stage. In this paper, 2D Henon maps are employed to all encryption stages including permutation, diffusion, and key stream generation. Unlike the pixels processed one by one in the diffusion stage in most image ciphers, two pixels are processed simultaneously in our scheme. The extensive security analyses have been carried out and the results demonstrate the high security of the proposed scheme.
