An Image Encryption Scheme Based on Hyperchaotic Rabinovich and Exponential Chaos Maps

An Image Encryption Scheme Based on Hyperchaotic Rabinovich and Exponential Chaos Maps

This paper proposes a new four-dimensional hyperchaotic map based on the Rabinovich system to realize chaotic encryption in higher dimension and improve the security. The chaotic sequences generated by Runge-Kutta method are combined with the chaotic sequences generated by an exponential chaos map t...
