提出了一个由四个半导体激光器通过相互耦合构成的混沌网状网络系统，研究了这种拓扑结构下各激光器的动力学行为、任意两个激光器之间的混沌同步特性以及参数失配对同步性能的影响，并对该系统的保密通信性能进行了分析。理论仿真结果表明，网状网络系统中各激光器在合适的相互耦合条件下均可呈现混沌输出，四个激光器输出的混沌信号可达到整体同步(即所有混沌信号之间都同步)或部分同步。基于该网络的混沌同步，可实现多用户之间信息的双向保密传输。

A chaotic mesh network system composed of four mutually coupled semiconductor lasers (SLs) is presented in this paper. For this system, the dynamical behaviors of each SL, the synchronization characteristics between arbitrary two SLs and the influence of parameter mismatches on the synchronization are investigated numerically, and the secure communication performance of such a system is analyzed. The theoretical simulation results show that all outputs from SLs in this mesh network system can route into chaos under suitable coupling condition, and global synchronization or partial synchronization can be observed for these four SLs. Based on chaos synchronization in this system, the bidirectional secure communication among multi-users can be achieved.
