A new image encryption scheme based on 3D Sine-adjusted-Logistic map and DNA coding

The chaos theory is a widely used technology for image encryption as its significant properties such as unpredictability and initial state sensitivity. In this paper, we introduce a new 3D Sine adjusted Logistic hyperchaotic system (3D-SALM), which is derived from the Logistic and Sine maps. Performance evaluation shows that it has good performance in ergodicity and orbit uncertainty. To investigate its applications, we propose a new random DNA coding scheme, the random coding rules are according to 3D-SALM sequences. This paper further introduces a new image encryption scheme (SALM-IES). In order to enhance the confusion of cipher-image, the principle of random diffusion and random confusion are fulfilled. Simulation results show that the proposed scheme can effectively resist various typical attacks, especially in the resistance to differential and cropping attacks.
