Abstract

In order to solve the drawbacks of small chaotic space and poor security when the traditional Henon map was implemented in cryptosystem, this paper designed an improved Henon map. Performance analysis in terms of bifurcation diagram, chaotic orbit, Lyapunov exponent and approximate entropy proved that the improved Henon map had larger chaotic space, better ergodicity and higher chaotic complexity, which made it applicable for developing secure cryptosystem. Based on the improved Henon map, this paper proposed a fast image encryption algorithm. The proposed algorithm consisted of multiple-block substitution and bidirectional block diffusion. In the multiple-block substitution process, it divided the plain image into some blocks with various sizes, and then scrambled these blocks. In the bidirectional block diffusion process, it redivided the scrambled image into several blocks with same size, and carried out the block diffusion operation to obtain the cipher image. Simulation results and security analysis demonstrate that the proposed algorithm is safe and efficient.
