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.
在研究杜芬繫統廣義混沌同步的基礎上,提齣基于此廣義混沌同步的數字保密通信的方案,將二進製信息調製為FSK信號,再由FSK信號驅動非自治混沌繫統髮齣混沌信號,噹繫統處于廣義混沌同步時,接收耑便可恢複齣二進製信息.從倣真結果看,此方案有效.

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.
