摘要：

提出了一种通过单驱动变量实现新型类洛伦兹系统混沌同步的方法,并将该方法应用于基于混沌掩盖的保密通信。由于驱动系统只需要向响应系统传递包含一个状态变量的单路信息即可实现混沌同步,使得该方法比已有方法具有更高的实用性。理论推导和计算机数值仿真实验表明了该方法的有效性。

Abstract:

A simple synchronization method by only transmitting a single driving variable for a new Lorenz-like attractor is proposed. Furthermore, based on the chaotic synchronization method, a secure communication system is proposed. Since chaos synchronization can be achieved by transmitting only one channel information contains a single variable from driving system to response system, this method is more practical. Theoretical deduction and computer simulation show the effectiveness of the proposed method.

Key words: chaos synchronization; secure communication; Lorenz-like chaotic system; single driving variable
