Chaotic Synchronization Secure Communications Based on the Lorenz Systems Switch

摘要

摘要: 该文提出利用Lorenz系统切换混沌同步实施保密通讯的方法。构建了有一定关联的两个Lorenz混沌系统，并通过选择器在系统间随机切换；用同一种控制方法既能实现不同Lorenz系统的混沌同步，又能实现相同Lorenz系统的混沌同步；发送系统可以在Lorenz混沌系统间随机转换，传输信道中混沌调制信号也随之不断变化；接收系统将混沌调制信号解调后，即可获取有用信号。由于发送系统的可选择性，导致保密信号的多样性和随机性，因此该保密通讯方法具有更好的保密性能。

Abstract: 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.
