The Study Of The Chaos Secure Communication Based On The Adaptive Inverse Control

Along with the proposing of the concept of information superhighway, the world scope information network is gradually forming.The information security is more and more important.The chaos signal have inherent characteristics of wide band and resembled the noise,it provides the method as the secure communication which highly keeps secret. A new development direction has been provided to the secure communication domain. In the chaos secure communication, the key question is to carry on the decipher with the reliable synchronized chaos method, and can over come the channel noise disturbance. This article in view of this question, in the separate chaos synchronous system, has designed the adaptive inverse controller based on the adaptive inverse control principle. In the separate chaos secure communication system,has designed the noise killer.Concrete content and conclusion as follows:First,introduced the merit of chaos secure communication and present researching situation, elaborate the popular chaos synchronized control methods and chaos secure communication encryption methods.Introduced adaptive inverse control principle and the modelling methods, and carried on the contrast analysis with the traditional adaptive control, highlighted its merit.Then analyzed the characteristic of separate chaos system synchronization in the noise existence situation, based on the adaptive inverse control principle, proposes the inverse control plan.Analyzed characteristic and merit of the recognize method based on the nerval network.Using the RBF nerval network realized discrete chaos system recognizing.Based on the adaptive inverse control principle,realized the nerval network controller design.The simulation result indicated that the method is effective. Analyzed the synchronization characteristic of discrete chaos system in the situation of existing channel noise. Based on the above method, designed the adaptive inverse control chaos synchronize dalgorithm, it has effectively over come the channel noise. The simulation result showed that the chaos system has realized synchronization.Last, introduced the former includes to discrete chaos secure communication system, eliminated the channel noise. The simulation result indicated the correspondence information precisely restorated.
