摘　　要：通过设计合适的状态观测器,实现了统一混沌系统的同步,并讨论了其同步性能,并在此基础上提出了两种新型混沌保密通信方案,其中一种不需要混沌同步即可实现保密通信。讨论了两种混沌保密通信方案的仿真性能,仿真结果证明了所述方案的有效性。Synchronization of unified chaotic systems was achieved by the design of a proper state observer and the synchronous capability was discussed. Two new methods for chaotic private communication were proposed, in one of which the chaotic synchronization was not required at all. The simulation performance of the two methods was discussed and results verified the effectiveness of the proposed methods.
