Synchronization of Discrete Sprott Chaotic Systems and Its Application in Secure Communication

In this paper, synchronization of discrete master-slave Sprott chaotic systems and its application in secure communication are presented. We utilize a discrete sliding mode scheme to solve the synchronization problem of discrete Sprott chaotic systems. The proposed scheme guarantees the synchronization between the master and slave discrete Sprott chaotic systems based on the use of Lyapunov stability theory. Moreover, the selection of switching surface and the existence of discrete sliding mode are addressed. Finally, the experimental results validate the proposed chaotic synchronization approach.
