摘　　要：根据Lyapunov稳定性定理,使用观测器方法实现混沌异结构同步。由连续系统稳定准则,在同步试验的基础上将异结构混沌同步应用于保密通信,对于给定的不同信号用混沌遮掩,混沌键控,混沌参数调制三种方法实现保密传输,在混沌参数调制方法中提出了提取能量均值解调有用信息的方法,并利用MATLAB仿真,证实方案的优越性和有效性。According to the stability principle of Lyapunov,this passage achieve synchronization of two different chaotic systems using observer. By the stability criteria of continuous system, it applied the synchronization of two different chaotic systems to secure communication in the basic of synchronization trials. For a given different signal, it apply the chaotic cover, chaotic shift keying and chaotic parameter modulation into the security transfer. Especially the passage proposed the plan of extraction of energy mean to demodulate the useful information in the method of the chaotic parameter modulation, and make lab of MATLAB to confirm the superiority and effectiveness of the program.
