Multiple-image Encryption Mechanism Based on Ghost Imaging and Public Key Cryptography

On the basis of ghost imaging, this paper proposes a multiple-image encryption scheme combining public key cryptography and Hadamard basis pattern. In the encryption system, a plurality of light paths are set, and the Hadamard basis patterns are used for illumination, so that each light path is concentrated in a bucket detector to obtain intensity values of all images. Then, all the detected inten...
