摘要：In recent years, Information security is a fast growing research field; image encryption is one of the important problems in the field of image information security. A number of Chaos based cryptosystem have been proposed, Most of them based on the traditional confusion-diffusion architecture. The draw backs of traditional architecture are Less sensitiveness in change of plain image and chosen/known plain-image attacks. In this paper, we propose A bit-level sub image blocks confusionand Circular Diffusion to provide the security of traditional architecture. Simulations have been carried out and the results demonstrate the superior security and high efficiency of the proposed scheme
