Abstract

In this paper, a fractional-order Chen system is discussed and analyzed by using the frequency-domain approximation method. Its chaotic characteristic can be observed by numerical simulation when the order is as low as 2.9. Then the existence of chaos is verified through the Lyapunov exponent diagrams, bifurcation diagrams, and phase orbits diagrams. At last, based on the fractional-order Chen system, a kind of double encryption algorithm is proposed and adopted to realize the image encryption. The experimental results and analysis show that the proposed method not only has the ideal effect of image encryption, but also has a high security of resisting the statistical attacks. That is, the proposed method is suitable and feasible for image encryption.
