| 摘 要： | 基于Lyapunov稳定性理论,研究了全局耦合网络的渐近同步,提出了一种全局混沌同步方案,并将其应用于保密通信.提出了一种新的混沌保密通信系统的实现方法,首先,在发送端将响应系统的信号与需要传输的有用信号进行合成加密,然后,将合成的混沌信号作用于发射系统进行二次加密;在接收端,信道传输的信号经过与发送端相同的混沌系统二级解调后恢复出原有用信号.以Liu系统为节点进行数值仿真,验证了结论的可靠性. |

| Abstract: | Based on Lyapunov stability theorem,the asymptotic synchronization of globally coupled network is studied,a method is proposed for global chaos synchronization,and applied to secure communication.Using two coupled identical systems,a novel method of chaos encryption is proposed,after encrypting in the two systems,information signal can be recovered exactly at the receiver end.Finally,the result of numerical calculation for the global connected networks with Liu nodes shows that the theorem is reliable. |
