Abstract

Digital image has the characteristics of large amount of data, high redundancy and strong correlation between pixels. Breaking the correlation between data and improving sensitivity is the key to protect image information. Aiming at how to quickly and effectively break the strong correlation between image pixels and improve the sensitivity of image data, this paper proposed a block cyclic DNA image encryption algorithm based on logistic chaotic map. The algorithm adopted the structure of secondary scrambling and primary diffusion. Firstly, it scrambled the plaint image by zigzag transform to break the strong correlation between plaint pixels. Secondly, it used the key generated by random sequence generator as chaotic parameters to ge-nerate dynamic DNA coding/decoding and operation rules, and encoded the scrambled plaint image by DNA to form the initial cipher. Then, using the DNA operation rule, it divided the initial cipher into blocks and cyclic DNA operation to complete the cipher diffusion, and counted and normalized the DNA bases into a quadratic chaotic key. It generated the dynamic step size rules by quadratic chaotic map, scrambled the cipher by Joseph variable step length, and formed the final cipher image by using the DNA decoding rules. The experimental results show that the cipher image has uniform pixel distribution, weak correlation between pixels, strong key sensitivity and large key space, which can effectively resist common attacks such as information analysis, violence, noise, clipping and so on.
