摘　　要：现代复杂通信系统具有分布式、规模大、接入信号多和并行传输等特征,其通信安全问题日益突显。在分析混沌族群系统的演化方法以及混沌族群系统的统一同步问题的基础上,构建三维空间混沌系统的转动模型。以Newton-Leipnik系统为研究对象,利用3路不同的通信信号,对混沌族群的演化、混沌族群系统的统一同步进行了仿真和验证。实验结果证明了该方法的有效性,应用前景良好。Modern complicated communication system has the characteristics of distributed,large scales,multiple-imput signals and parallel transmission,which result in the increasing urgent problem of communication security.Based on the analysis on the evolution method and the unification-synchronization problem of the chaotic group system,a rotation model of 3D chaotic system was established.With the Newton-Leipnik system as study object,three different types of communication signals to simulate and validate the evolution of chaotic group,and the unification and synchronization of the chaotic group system was utilized.Experimental results show that the method presented in this study is effective and has a good prospect for the application.
