摘　　要：分析了一个新自治混沌系统的基本特性,针对该自治系统同步控制及在保密通信中的应用进行了仿真研究,用混沌掩盖的方法将该同步方法应用于保密通信,将有用的信息信号调控到混沌系统的状态变量中进行加密,与混沌信号的输出信号一起传送到接收端,发送系统和接收系统同步以后,在接收端解密恢复出信息信号.仿真结果表明,该方法可以实现单调快速同步,应用于保密通信可以达到掩盖有用信号的目的,并且可以无失真地恢复有用信号.Some basic properties of a new chaos system were analyzed. The issue was investigated on chaotic synchronization and its application of secure communication based on the new system. Then this method was applied to secure communication through chaotic masking. The information signal was recovered through a decrypted synchronized receiver. Simulation results show that the method can realize monotonous synchronization. Furthermore, the information signal can be recovered undistortedly when applying this method to secure communication.
