A Novel Impulsive Control Scheme of Chua Chaotic Synchronization

Most chaotic synchronization control methods have some flaws which increase the security risks of the communication system. Attacker can reconstruct the chaotic system or estimate parameters by using the information of the chaotic system. In this paper, we propose a hybrid Chua chaotic synchronization control scheme which contains both continuous chaotic system and discrete chaotic system. We proved that two systems can get synchronized without control signal transmitting which has reduced the risk of the security. The chaos-based secure communication system can be designed based on our scheme.
