一种新的多级混沌系统在保密通信中的应用

A New Multistage Chaotic System and Its Application to Secure Communication

就混沌通信问题，提出了一种多级混沌保密通信系统的实现方法。研究表明，该方法明显改善了混沌保密通信系统的安全特性和有效带宽。给出的仿真实例也证明了这种方法的有效性。最后，针对实际应用，指出了需要进一步研究和解决的问题。

In this paper, a multistage chaotic system for secure comm unication is proposed. The method improves greatly the secure property and the bandwidth of the chaotic secure communication system. The exa mple that we give demonstrates the efficiency of the method. At last, in view of the practical application, the problem which need further r esearch and solve is discussed.
