A hybrid cryptosystem based on plaintext-related ghost imaging and elliptic curve public-key cryptographic algorithm (ECC) is proposed in this paper. Thereinto, the ECC algorithm is used to protect and distribute session keys and the optical encryption system with session keys is used to encrypt and decrypt images. Thousands of phase-only mask keys can be replaced by parameter keys in this method, which successfully reduces the pressure of key storage. With dynamic updating session keys, the attacks are effectively prevented and the security resilience is enhanced. In addition, the utilization of an ECC cryptosystem solves the inevitable problem of key management and dispatch in conventional ghost imaging encryption system. The feasibility, security and robustness of the method are further analyzed through computer simulations.

“…It utilizes the properties of quantum entanglement to achieve non-local image transmission [1]. Ghost imaging has various advantages over traditional optics due to the existence of correlation characteristics, such as anti-interference ability, weak optical imaging capability [2][3][4], and encryption capability. However, since ghost imaging is transmitted through the optical path, the resolution remains limited by optical diffraction conditions.…”

Ghost imaging is a novel imaging technique that has various advantages over traditional imaging. However, most of the existing works on this technique do not achieve a better resolution than the diffraction limit. In this work, we presented a ghost imaging system with plasmonic structure illumination microscopy that achieved super-resolution imaging. The resolution reaches three to four times of the diffraction limit with surface plasmon polaritons and structure illumination microscopy theory. Since it can produce super-resolution images, this method has important implications in medical fields, such as in microimaging and endoscopy. We used the gamma-gamma intensityfluctuation model to simulate the ghost imaging system in an atmospheric turbulence channel. By setting proper values of the transmission distance and refractive-index structure parameter, we obtain the peak signal-to-noise ratio (PSNR) performance and symbol-error rate (SER) performance. Finally, the PSNR and SER are used to evaluate the imaging quality, which provides a theoretical model to research the ghost-imaging algorithm further.

A method for the optical data encryption and decryption based on the sweeping computational ghost imaging is proposed. This method is governed on reconstructing the ghost imaging by one-by-one sweeping of rows or columns of the random generated matrices. Proposed encryption in this paper is deﬁned by these sweeping row and column matrices and basic mathematical operators between them. Introduced encryption can be employed as symmetric and asymmetric encryptions. In the symmetric system, cross-operator and the row and column matrices were assumed as private keys, deﬁning the four basic operators as decryption keys. Whereas, in the asymmetric system, permutation of three possible cases was considered as private keys, leaving cross-operator and row and column selection sequence as public keys. The number of pixel changing Rate (NPCR) as a parameter that evaluates the strength of image encryption versus differential attacks was calculated for each case which show high security data transfer to the user. In the asymmetric systems, even with eavesdropping 50% of data, no useful information was obtained from the image or data. In the symmetric systems, with eavesdropping 100% of data, no useful information was obtained by multiple attacking the encrypted data. Offered high security along with achievable high speeds and compact data packages classify sweeping computational ghost imaging among the best applicable methods for optical data encryption.
