Nonlinear Synchronization of a New Lorenz System and its Application in Secure Communication

In this paper, the nonlinear synchronization scheme is proposed for secure communication via a new Lorenz chaos system. Based on the time scale transformation, a new chaotic circuit is designed. Then the nonlinear synchronization is realized by using nonlinear feedback control method. The experimental results show that the nonlinear synchronization method is effective, and can realize the nonlinear synchronization of the drive circuit and the response circuit composed by the chaotic system, and apply it to the secure communication, which can make the receiving and sending information consistent, and make the secure communication system more confidential.
