Mismatch synchronization based on 4D memristive chaotic system and its application in image encryption

Abstract

A four-dimensional memristive chaotic system is proposed, and its dynamical characteristics are analyzed through conventional methods. In this system, transient chaos and bursting oscillations of the number of spikes controlled by parameters are also found. This paper also designs physical circuits and digital circuits to confirm the existence of chaotic systems. Additionally, a mismatch synchronization system is introduced, and the synchronization control is achieved using mismatch synchronization principles. Mismatch synchronization is integrated with RNA operation to develop an image encryption algorithm. The analyses show that the image encryption method proposed exhibits better performance.
