摘要
混沌反控制为混沌控制的一个研究方向,已成为人们研究的热点.探讨混沌反控制理论、混沌反控制方法,对一类非线性系统,设计控制器,得到混沌化的系统,并将该系统应用在图像加密中.仿真实验表明:该非线性系统的混沌反控制在图像加密中取得了很好的加密效果,密钥空间大,扩散扰乱性能好,能够抵抗各种攻击.
Chaos anti-control is one research direction of chaos control, it becomes people's hot research. It discussed theory and method of chaos anti-control; then designed a controller base on one kind of nonlinear systems, obtained chaos system ; at last, the system was used in image encryption. The experimental resuhs demonstrate that chaos anti-control of the nonlinear systems had good efect in the encryption algorithm. It has not only a large key space but also a very sensitivity with respect to the secret key and the original image. The encryption algorithm has perfect diffusion and confusion properties and it can resist the various attacks.
