蔡氏电路混沌同步保密通讯

两个相同的蔡氏电路(Chua’s Circuit)互相耦合可以实现混沌(Chaos)同步是混沌研究的一个重要成果．也是探索蔡氏电路开发应用的基础。应用蔡氏电路的同步特性实现保密通讯是当前蔡氏电路开发应用研究的一个主要方向。本文在介绍蔡氏电路混沌同步特性的基础上，讨论主—从式蔡氏电路同步保密通讯系统及实现双向通讯和无线传输的可行性．并对这种保密通讯系统的安全性与鲁棒性(Robustness)作了简要的分析.

Secure Communication via Synchronized Chua''''s Circuits

Chua's circuit is a well-known simple electronic circuit to be chaotic. The sruchronization between two identical Chua's circuits can be achieved when they are properly coupled. This is an important result of the study on chaos, and is fundamental to the exploitations and applications of Chua's circuit.Applying the poverty of chaos synchronization to secure communication becomes currently a very interesting topic for Chua's circuit. The secure communication systems via synchronized Chua's circuits, which are connected in a master-slave confirmation, are proposed and the feasibility tO implement hi-directional and wireless secure commtmications, rmpectively, is presented in this paper. The security and robustness of the secure communication are also brieny discussed.
