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 informationbearing signal. The modulation process is embedded in the dynamic iteration process of Generalized Hènon map. In the receiver, a nondynamic system which has the same form as Generalized Hènon map is used to retrieve the chaotic carrier from the received signal and then the informationbearing signal is recovered. The results show that the method has the advantages of reliable synchronization, good security as well as the easiness in practice.
