| 摘 要： | 在研究杜芬系统广义混沌同步的基础上，提出基于此广义混沌同步的数字保密通信的方案，将二进制信息调制为FSK信号，再由FSK信号驱动非自治混沌系统发出混沌信号，当系统处于广义混沌同步时，接收端便可恢复出二进制信息。从仿真结果看，此方案有效。

| Abstract: | The generalized synchronization(GS) of Duffing system is investigated,then a digital secure communication scheme based on the generalized chaotic synchronization is proposed.The binary messages to be transmitted are firstly modulated by FSK modulation,then the FSK signals drive non-autonomous chaotic system to transmit chaotic signals.In the receiver,the binary messages can be recovered when the chaotic systems achieve generalized synchronization.Simulation results show effectiveness of the scheme. |
