Synchronization of Unified Chaotic Systems and Application to Secure Communication

摘要

Synchronization of unified chaotic systems and application to secure communication are discussed. A parameter adaptive rate and proper control for synchronization of unified chaotic systems in the present of uncertain parameters and external disturbances are presented, which can lead to achieve quickly synchronization between the drive chaotic system and the response chaotic system. After transformation of the useful signal, a secure communication based on chaotic masking is derived, this can guarantee the useful signal recover quickly from the receive system. Simulations show that the synchronization of unified chaotic systems and secure communication are feasible and effective.
