Abstract :
This paper focuses on how to synchronize two chaotic systems, when they are connected, using a variable time delay channel. Applying the proposed technique for secure communication, an encryption algorithm that can be used for text messages, images and recorded voice with high security, is also presented. The simulation results reveal that signals to chaos ratio of -246dB and synchronization have been achieved.
