Paper Abstract

In this paper, we propose a robust 3D image encryption scheme based on computer-generated hologram (CGH) in fractional Fourier domain. The layer-based Fresnel transform is utilized to generate one phase-only CGH, which is then decomposed into two phase-only masks (POMs) by pixel superimposed method. Encryption was realized by using the created POMs in two cascaded fractional Fourier transform domains while two decryption keys are produced in the encryption process. The cryptosystem is asymmetric and high resistance against to the various potential attacks, including chosen-plaintext attack (CPA). The proposal is supported with computer simulation results. Simulation results and security analysis verify the feasibility and effectiveness of the proposed encryption scheme.
