Abstract

In order to improve the security of cipher code in encryption system and obtain better diffusion effect of the encrypted image, an image encryption algorithm based on affine cipher is presented. The algorithm first scrambles pixels position by using Lorenz chaos sequence, and then introduces the affine cipher of classical cryptograph to diffuse and confuse pixel values. Theoretical analysis and experimental results show that the algorithm has high sensitivity keys, better security of encryption, and excellent diffusion and confusion properties. The algorithm has a better diffusion effect compared with the XOR encryption performance.
