In this paper, a color image encryption method using the memristive hyperchaotic system and deoxyribonucleic acid (DNA) is proposed. First, pseudo-random sequences are generated by keystream generation mechanism based on plain image. Due to this, has complex dynamical behavior highly sensitive initial conditions, proposed random which also dependent images. Second, permutation cycle-shift operation designed eliminate correlations between adjacent pixels in Then, scrambled processed DNA increase ability defense brute force attacks. Finally, cipher obtained after diffusion interaction among red, green blue components. Experimental analysis performance comparisons show that high security, good efficiency strong robustness under different
