An Image Encryption Scheme of Logistic Modulation Using Computer-Generated Hologram and Chaotic Map

Abstract EN

We introduce an image encryption method based on computer-generated hologram (CGH) and two-dimensional Sine Logistic modulation map (2D-SLMM).

We combine CGH and 2D-SLMM to improve encryption security.

During the encryption process, the hologram needs to be logistically modulated by 2D-SLMM.

This logistic modulation technique can avoid complex algorithms.

Simulation results and security analysis demonstrate that the proposed approach has a high security level, good invisibility of image information in ciphertext, large key space, and strong robustness.
