摘　　要：基于线性反馈同步的理论,实现了统一混沌系统的线性反馈同步的控制,并将该混沌同步方式应用于混沌参数调制的保密通信系统中。在系统的发送端利用发送的信息信号调制混沌系统的参数,将信息信号隐藏在混沌信号中,在系统的接收端利用混沌同步信号提取出相应的混沌系统参数,进而恢复出所传输的信息信号。仿真结果表明其同步时间短,在保密通信系统的接收端恢复出信息信号非常逼近发送的信息信号,具有较强的保密性和实用性。This paper researched the linear feedback synchronization of the unified chaos system,which was applied in the secure communication based on the chaotic parameter modulation.It used information signals to modulate some parameter of the unified chaotic system in the sending terminal,and then in the receiving terminal,it obtained the chaotic content based on the chaotic synchronization signal,then it recovered the information signals effectively.The simulation results show that the synchronization time is very short and the recovered signals are close to the information signals and it can realize secret communication successfully,having strong security and practicability.
