Multiple-Image Encryption Mechanism Based on Ghost Imaging and Public Key Cryptography
Abstrak
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 intensity values are encrypted by using public key cryptography algorithm to obtain the final ciphertext. The use of basis patterns allows for high-quality reconstruction. In addition, randomness in the permutation operation and public key cryptography provide a strong security feature for the encryption system. The multiple-image encryption scheme solves the crosstalk problem among images. The basic principle of the encryption scheme is theoretically analyzed, and the feasibility and security of the proposed method are verified by numerical simulation.
