摘　　要：为探讨超混沌同步机制,研究其在保密通信中的应用,以超混沌chen系统为研究对象,给出了超混沌系统的Matlab仿真步骤。利用复制、耦合等方法实现了耦合同步法仿真,借助于等间隔脉冲对收端系统进行控制,实现了脉冲同步法仿真。结果表明:超混沌耦合同步中,耦合系数大,则同步时间短;脉冲同步中,脉冲周期小,则同步时间短。This article discussed the hyperchaos synchronization mechanism, researched its application in security communications. Aimed at hyperchaos system, the article proposed the simulation phases of Matlab. By means of copying, coupling, it realized the coupling synchronization simulation. Furthermore, by means of equally spaced impulse to control the receiving end system, the article realized the impulse synchronization simulation. The results show that in the hyperchaos coupling synchronization, the bigger the coupling coefficient is, the shorter the synchronization time is; in the impulse synchronization, the smaller the period of impulse is, the shorter the synchronization time is.
