We present a new compact scheme to ensure high performance optical encryption. In this scheme, the encrypted data and the security key are recorded without need for a reference arm, resulting in a significant decrease in the size and complexity of the cryptosystem. The efficacy of the compact scheme to protect data is verified by encrypting and decrypting different inputs. We also test the resistance to both random noise and data loss. Additionally, the potential of the system is evaluated by encoding the data to be encrypted by means of a customized data container. In this way, we achieve a data volume reduction of 97% for the encrypted data while allowing for noise-free information recovery using the proposed cryptosystem. We experimentally demonstrate both encryption and volume reduction, confirming the validity and applicability of our proposal.

“…Este nuevo contenedor ha servido de base para novedosas aplicaciones con operaciones XOR (Qin & Zhang, 2017), algoritmos de recuperación de fase (Qin, et al, 2018b), imágenes fantasmas (Liansheng, et al, 2019), criptosistemas asimétricos (Kumar & Nishchal, 2019) e, inclusive, implementaciones en el dominio de Fresnel (Jaramillo-Osorio, et al, 2020a). Es importante tener en cuenta que la recuperación libre de ruido está limitada a los caracteres que se puedan codificar y decodificar usando los contenedores de información.…”

“…Optical information security has attracted wide research interests in the field of information security due to the superior capabilities of high-speed, parallelism, and high encryption dimension [1], [7]. Especially, the double random phaseencoding technique (DRPE) based on 4-f system, which was firstly designed by Refregier and Javidi in 1995 [8], are extensively studied in recent years.…”

et al. 2020

Conventional phase-truncation-based double-image encryption (PT-DIE) scheme suffers from the phase retrieval algorithm-based attack, and information disclosure issue. In this paper, we introduce cylindrical diffraction and position multiplexing into the PT-DIE scheme. Through position multiplexing, double-image are integrated together. Then the integrated image is encoded into a real-valued cyphertext and two phase-only keys (POKs) by cylindrical diffraction. The decrypted images are acquired with two POKs by inverse cylindrical diffraction, and because of that, the phase retrieval algorithm-based attack and the information disclosure issue have been thoroughly conquered from a theoretical and experimental point of view. Furthermore, the proposed scheme can be extended to encode multi-image without changing original system architecture, and incurring additional computing burden. Simulation results have been manifested the validity and the security of the proposed scheme.INDEX TERMS Nonlinear images encryption, position multiplexing, cylindrical diffraction, information disclosure, phase retrieval attack.
