Abstract: An image compression encryption scheme on the strength of a conservative chaotic map, compressed sensing (CS) and DNA method is proposed. Built on the hash algorithm, a novel algorithm for generating the initial state of the chaotic map is designed, which makes the algorithm resistant to chosen-plaintext and known-plaintext attacks. The pseudo-random sequences which are produced by the conservative chaotic map are devoted to constructing the measurement matrix of CS and control the encoding and operation mode of DNA, which improves the complexity of the cryptosystem. In addition, a novel Integrated Cyclic Crossover and Mutation algorithm (ICCM) based on DNA method is proposed. ICCM simultaneously completes the scrambling and diffusion of images based on the loop structure, which greatly enhances the security of the algorithm. Experimental results and a number of security analyses demonstrate that the scheme has excellent performance and robustness, and has good resistance to various attacks.
