Research on the chaotic group secret communication of the distributed,large-scale and multi-signal system

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.
