Conventional cryptography in higher layers of protocol stack has been studied as a data protection technique from an unauthorized party by converting secret data into a non-readable binary form. In this work, we leverage an OAM-wave-based transmission as an additional layer of physical security to be used with data encryption. A trustworthy key distribution mechanism for symmetric cryptography protocol is proposed by exploiting randomly hopping among the orthogonal OAM-wave modes and phases. Keccak block generates randomness for OAM modes, and AES is employed for encryption. This work provides physical-layer security, which is compatible with any higher layer encryption techniques. The hardware is implemented in 65nm CMOS technology, and post place-and-route simulation results are presented.","abstract_html":"As technology progresses and an ever-increasing number of digital data are transmitted day to day, securing data has emerged as a major field of research.
