Abstract :
In this paper we investigate the adaptive synchronization applied for image encryption. Based on Lyapunov stability theory, the adaptive controller with its corresponding parameter update law is designed such that uncertain unified chaotic system can synchronize asymptotically with cellular neural networks. The numerical result illustrates a robust cryptosystem is feasible for transmitting an encrypted image.
