摘要
Abstract
In this paper, a novel four-dimensional hyper-chaos system with four-wing chaotic attractor is proposed, and this system is applied to digital image encryption. The basic dynamic characteristics such as phase diagram, equilibrium point, Lyapunov exponent spectrum, bifurcation diagrams, Poincare section are analyzed. Changes of parameters of Lyapu-nov index spectrum and bifurcation diagram are analyzed in detail. An artificial circuit of the four-wing hyper-chaos sys-tem is designed and the result of the simulation are consistent with theoretical analysis, the hyper-chaos behaviors of the system is verified. Finally, the new system is applied to image encryption, histogram of the image and the correlation between adjacent pixels are analyzed before and and after the encryption. Obviousness the effect of image encryption is well.关键词
