Based on 2D cellular automata and Logistic map,a novel image encryption is proposed.The proposed scheme utilizes Logistic map to construct a nonlinear coupling structure for scrambling the pixel matrix of the plain image.Then a pseudorandom number matrix is formed combining the chaotic characteristics of cellular automata.Simulation experiments and security analysis demonstrate that the proposed algorithm can reach a satisfactory encryption performance and has large enough key space.Furthermore,it is highly sensitive to the secret keys.The cipher image has excellent diffusion and statistical properties and could resist exhaustive attack,sensitive attack and statistical attack,etc.
