Adaptive synchronization for a class of novel uncertain chaotic systems with channel delay and its applications to secure communications

This paper investigates the asymptotical synchronization problem of a class of novel uncertain chaotic systems with channel delay. Furthermore, the parameters of the chaotic system in the synchronization systems are assumed to be fully unknown. It is reasonable since the sending end usually is located on the remote site. By virtue of the definition of lag synchronization and adaptive control idea, the asymptotical synchronization for a novel type chaotic systems is implemented. The above results will provide theoretical foundation for the secure communication applications based on chaotic synchronization. Simulation results are given to verify the effectiveness of the proposed adaptive synchronization method.
