| 摘 要： | 以复杂网络为背景,根据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,并在同步的基础上研究了节点之间的保密通信,用混沌遮掩的方法将该同步方案应用于保密通信,将有用的信息信号调控到混沌系统的状态变量中,与混沌信号一起传送到接收端,发送系统和接收系统同步以后,在接收端恢复出信息信号。最后以Chen系统为节点进行数值仿真,验证了结论的可靠性。

| Abstract: | Taking the complex network as the background,based on Lyapunov stability theorem,the asymptotic synchronization of globally coupled network is studied in this paper,and a method is proposed for global chaos synchronization.Then this method is applied to secure communication through chaotic masking.Used two coupled identical systems,after encrypting in the two sys-tems,information signal can be recovered exactly at the receiver end.Finally,the result of numerical calculation for the global connected networks... |
