摘要
混沌是确定性混沌，有确定的演变规律，因而它有可利用的基础，将混沌信号与有用信号迭加发送，在接收端再利用混沌信号解码，是实现混沌保密通信的基本思路，混沌电路满足某些条件时可以锁频，为加载信息提供了可能和方便．本文指出，著名的Ｌｏｒｅｎｚ系统具有严格的对称性，可将该特性用于同步混沌系统，以实现保密通信，文章还详述了实现混沌保密通信的方案和技术条件，就利用同步混沌电路和对称混沌信号实现保密通信进行了探讨．
Chaos is definite, and because it has definite developing regularity, it has the bases to be utilized. Put chaos signals and useful signals together to send and on the receive side use the orginal chaos signals to decode. This is the basic thinking of realizing security communication with chaos. Chaos circuit can lock frequency when some cerain conditions met. This makes it much easier to carry information. The paper points out that the famous lorenz System has the most strict property of symmetry. Moreover, this prosperity can be used in synchronous chaos system to achieve secuity communication. This article has expounded the scheme and technical condition to realize chaos securty communication in detail. It has also put forward a research direction of applying Lorenz System and synchronous chaos circuit to realize chaos security communication.
