Abstract :
To realize the secure communication based on chaos modulation, this paper designs an adaptive sliding mode synchronization scheme of a class of chaotic systems and a secure communication scheme. The secure information can be hided in the right hand side of the drive system equation, which represents a class of chaotic systems. The drive system and the response system are synchronized by an adaptive sliding mode controller. The secure information is looked on as a kind of disturbances and is extracted in the parameter of the controller by the adaptive law. Simulation results show the effectiveness of the chaos synchronization law and the secure communication scheme.
