Control of feedback system by small nonlinear signals realizes chaotic control and synchronization of the system with chaos and hyper-chaos.

利用非线性的小信号对反馈系统的控制，以实现一个具有混沌和超混沌特性的反馈系统的混沌控制和同步。

This paper USES chaos anti-control idea to generate a hyper-chaotic system, and USES the pseudo-random feature of hyper-chaotic system to design a stream cipher.

应用混沌反控制思想产生超混沌，根据超混沌系统的伪随机特性进行流密码设计。
