Chaotic Synchronization Secure Communications Based on the Lorenz Systems Switch
基于Lorenz系统切换混沌同步的保密通讯

A chaotic synchronization secure communication method based on several Lorenz systems switch is proposed. These Lorenz systems are built,which are relevant and can be switched each other via the choicer. Chaotic synchronization of these systems is realized using same nonlinear feedback control method. The transmitter can be switched discretionarily among several chaotic systems,bring on ceaseless changing of the chaotic carriers in transport channel. In the receiver,the chaotic carriers are retrieved from the received signals,then the information signals are recovered. The experiment result shows that this chaotic synchronization secure communications method based on several chaotic systems switch is better in security because of the transmitter can be switched and the chaotic carriers can be changed discretionarily.
