This paper presents a digital image encryption and decryption algorithm based on bit-planes and improved one-dimensional chaotic maps. Firstly, a simple and efficient new chaotic map is constructed by using two existing one-dimensional chaotic maps to generate random sequences for scrambling and diffusing the original image. Secondly, the original plain-image is decomposed into 8-bit planes, and the generated chaotic sequence is used to change the positions and values of the pixels to achieve the effect of scrambling and diffusion. Finally, the decomposed image is merged into gray image with 256 grayscales, and then the encrypted image is obtained by block shuffling operation. Experimental results show that the algorithm has good robustness and security. It can resist various attacks as well.
