Hyperchaotic dynamical system based image encryption scheme with time-varying delays

In this paper, we propose a 4D chaotic image encryption technique based on a dynamic state variables selection mechanism to improve the effectiveness and security of chaos-based image cryptosystems. Experimental outcomes of our scheme demonstrate better security against many known attacks, as well as high efficiency.
