一种基于混沌调制的保密通信方法

Secure Communications Method Based on Chaos Modulation

提出一种适合较大动态范围信息信号的混沌调制通讯方法 ,由于该方法允许较大幅度的信息信号 ,从而提高了通信的安全性。在接收端 ,用一个由自适应线性神经元 (Adaline)构成的控制器来维持收发系统的混沌同步 ,并通过检测Adaline权值的变化规律恢复出信息信号。以蔡氏电路为例进行了数值模拟 ,结果表明该方法是可行的。

Secure communications method for higher level of information signal based on chaotic modulation is proposed. In this method, because the level of information signal can be equivalent to the level of chaotic signal, the degree of security is high. At the receiving end, an Adaline maintains the chaotic synchronization of transmitting and receiving systems and simultaneously recovers information signal. Chua's circuits is considered as illustrative example to demonstrate the effectiveness of the proposed method.
