PDFAbstract: A novel image encryption algorithm based on DNA coding and the Two-dimensional logistic chaotic map is presented in this paper. The proposed encryption algorithm consists of three parts, DNA coding, permutation, and diffusion. First, the image is encoded by DNA coding, then, the DNA coded image is permutated by using the 2D logistic chaotic map. Finally, the image is diffused by using the 2Dlogistic chaotic map to get the encrypted images. Simulation results show that the proposed algorithm provides good encryption effect, high performance and high sensitivity.
Keywords: Image encryption, DNA operation. 2D logistic chaotic map
