| 摘 要： | 本文提出了一种基于细胞神经网络超混沌同步系统的双通道保密通信系统。用降维观测器思想实现了四阶细胞神经网络超混沌系统的高精度同步，并将其用于双通道混沌保密通信：一个通道传送与信息信号无关的混沌系统的输出信号实现高精度同步，另一个通道传送用混沌信号加密的信息信号。由于同步和加密信号分开传送并且采用了超混沌系统，所设计的保密通信系统具有更高的保密性。

| Abstract: | A two-channel secure communication system based on the synchronization of hyperchaos of cellular neural network(CNN) is presented. Based on the reduced-order state observer, an approach of synchronization of hyperchaos of four orders CNN is proposed. The hyperchaotic property is used in the two-channel communication system: the output of a chaotic transmitter is sent only for synchronization, without concern with the information signal, while the other channel transmits a signal generated from a highly nonlinear function of both the chaotic states and the information-bearing signal.Due to the hyperchaotic characteristics and the separation of the synchronization and the encryption of the information-bearing signals, the security of the communication system is improved. |
