基于限幅特性非线性三阶自治电路的混沌遮掩保密通信

Secure Communication Based on Nonlinear Third-Order Chaotic Circuit

设计了一种限幅特性非线性三阶自治混沌保密通信电路系统。该系统利用串联同步三阶自治混沌电路进行信号混沌遮掩保密通信。有用信号隐藏在混沌参数中,混沌复合信号作为传送信号,在发送端和接收端之间传送。利用接收端响应系统与发送端驱动系统达到同步,可无失真地将有用信息信号检出。该方法设计简单,易于实现,并且同步速度快,实现了高质量的信息保密传送,具有很好的可行性。

A nonlinear third - order chaotic circuit system is used to secure communication. The system realizes secure communications by using a series type synchronization of nonlinear third -order chaotic circuit. Only one chaotic signal, which carries information,is needed to transmit to the receiver, secure communication with high quality can be achieved. Simulation experiment shows when signals are transmitted the information can be detected and accurately restored.
