单向耦合洛伦兹混沌遮掩保密数字通信电路

Unidirectional coupling Lorentz circuit for secure communications with digital signals masked by chaos

给出了一种可高质量传送数字信号的保密通信系统,该系统利用耦合同步洛伦兹混沌电路系统进行数字信号的混沌遮掩传送.模拟实验表明,传送信息保密性好,在接收端用同步的混沌信号将信息信号检出并整形后可无失真的恢复所传送的数字信号.

A circuit system is presented to accomplish secure communications well. Digital signals are masked by coupling synchronized Lorentz chaos. Simulation result shows that the circuit system is stable and reliable, and the modulation can be detected and accurately restored by using the synchronous chaotic signal at the receiver.
