The Synchronization Of Complex Network And It's Application In Secure Communication

Network is a kind of widespread phenomenon between nature and human society. It is composed by many nodes with special link. Recently, complex network has been an active research of the nonlinear subject. This new technology promises to have a significant impact on many novel engineering applications. The challenging research field has become a scientific inter-discipline involving many other fields. In this paper, my dissertation mainly focuses on the chaos synchronization of complex network and secure communication. The main content is depicted as follows:1. To the synchronization of complex network in the research background and study conditions are proceeded very full-scale introduction and summaries.2. A general introduction about classical complex network models and the dynamical behavior is presented in chapter 2, it is useful for us to understand complex network.3. Considering the three bidirectional coupled nodes in the complex network, the sufficient condition for the global synchronization and asymptotical stability based on the Lyapunov stability theorem and matrix transformation. Unlike the approaches were used in most researches, the complex network is not linearized in this paper. Both theoretical analysis and simulation result show the effectiveness and feasibility of the method.4. On the foundation of the third chapter of research complex network's synchronization, discussed the use chaos system synchronization to carry on the security communication. A node of tree nodes is regarded as the transmitter, one other node is regarded as the receiver and digital signals are masked by coupling synchronized chaos. The modulation can be detected and accurately restored by using the synchronous chaotic signal at the receiver.
