超Lorenz 混沌系统的同步及其在保密通信中的应用

为了加密并准确解密传输的信息,将超Lorenz混沌系统的同步应用在保密通信中。基于线性稳定性定理,对超五阶Lorenz系统实现了超混沌系统的输出反馈控制同步,设计了超混沌系统的输出反馈控制器,实现了响应系统与驱动系统的同步,并将同步的混沌系统应用到混沌掩盖保密通信中。仿真结果表明,超Lorenz混沌系统能够快速达到同步,且在混沌掩盖通信方案中,有用信号可以有效地在接收端恢复出来。

Synchronization of Hyper Chaotic Lorenz System and Its Application in Secure Communications

In order to encrypt and decrypt exactly the transformed information,the synchronization of hyper chaotic Lorenz system was proposed to realize secure communications.Based on the linear system stability theory,an output feedback controller was designed to get the output feedback controlling synchronization of hyper chaotic Lorenz system.Also,the synchronized system was used in chaos masking approach.Simulation results show that the synchronization of hyper chaotic Lorenz system was realized fast,and the usef...
