摘　　要：提出了一种新的混沌同步及保密通信方法，即利用广义Ｈèｎｏｎ映射所产生的混沌信号作为载波，以有用信息对广义Ｈèｎｏｎ映射的参数进行调制，并将此调制过程嵌入到广义Ｈèｎｏｎ映射的动态迭代过程中，而在接收端通过一个具有广义Ｈèｎｏｎ映射形式的非动力学系统从接收信号中提取混沌载波，进而恢复有用信息．结果表明，该方法同步可靠、保密性好且易于实现．A new synchronization and secure communication method is proposed. The chaotic signal generated by Generalized Hènon map is used as a carrier and then the parameter of Generalized Hènon map is modulated by an informationbearing signal. The modulation process is embedded in the dynamic iteration process of Generalized Hènon map. In the receiver, a nondynamic system which has the same form as Generalized Hènon map is used to retrieve the chaotic carrier from the received signal and then the informationbearing signal is recovered. The results show that the method has the advantages of reliable synchronization, good security as well as the easiness in practice.
