| 摘 要： | 提出了一种新的基于混沌同步的保密通信方案。首先在发射端和接收端分别构建一个驱动系统及相应的响应系统。在发射端将信息信号调制到混沌变量中成为混沌传输信号,然后基于Lyapunov稳定性理论使两混沌系统达到同步,在接收端对混沌传输信号进行解调从而恢复出信息信号,混沌系统的初始条件和系统参数作为解调密钥。理论分析和数值仿真结果表明该方案是可行的。

| Abstract: | A new secure communication scheme is proposed based on chaotic synchronization.First a drive system and corresponding response system are built up respectively on the transmitting terminal and receiving terminal.The information signal is modulated on the transmitting terminal and turned it into chaotic transmitting signals,and then based Lyapurov stability theory; synchronization is introduced for the 2 chaotic systems.The chaotic signals are demodulated at the receiving terminal for the purpose of restoring the information signal.The initial condition and systematical parameters of the chaotic system are deployed as the key for demodulation.Theoretical analysis and numerical simulation results show that the scheme is feasible. |
