摘要
本文以复杂网络为背景,基于Lyapunov稳定性理论,研究了全局耦合网络的渐近同步,并提出一种全局混沌同步方案.在此基础上,将其应用到了保密通信中,将有用信号与混沌系统中的状态变量调和在一起,然后将混合信号传送到接收端,当发送系统与接收系统同步以后,在接收端恢复出有用信号.最后以Lorenz系统为节点进行数值仿真,验证了结论的可靠性.
Take the complex network as the background.Based on Lyapunov stability theorem, This assay studies the asymptotic synchronization of globally coupled network, a method is proposed for a global chaos synchronization, and it is applied to secure communication.Using two coupled identical systems, after en-crypting 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 Lorenz nodes shows that the theorem is relia-ble.
