Encryption and Decryption of Communication Systems Using the CMAC-Based Chaotic System Synchronization Technique

A Cerebellar Model Articulation Controller (CMAC) is designed for the synchronization control of chaotic system used for the encryption and decryption of communication systems. Chaotic systems are important nonlinear systems that display complex and unpredictable behavior. Since the architecture of CMAC is small and it can learn fast, so it is suitable for high speed signal processing. The audio and image to be transmitted can be mixed into chaotic systems for encryption transmission, thereby preventing the massage being known by others; and finally use the synchronization of chaotic system to decrypt the correct information at the receiving end. The synchronization of chaotic system can be controlled by using a CMAC. By adjusting the controller parameters, CMAC can achieve fast and stable control for decrypting the original signals.
