A comprehensive survey on 6G-security: physical connection and service layers

Discover Internet of Things
After adopting 5G technology, businesses and academia have started working on sixth-generation wireless networking (6G) technologies. Mobile communications options are expected to expand in areas where previous generations could not do so.

Physical Layer Security of Hybrid Satellite-FSO Cooperative Systems

IEEE Photonics Journal, 2019
In this paper, we study the physical layer secrecy performance of a hybrid satellite and free-space optical (FSO) cooperative system. The satellite links are assumed to follow the shadowed-Rician fading distribution, and the channel of the terrestrial ...

Physical-Layer Security in Free-Space Optical Communications

IEEE Photonics Journal, 2015
The communication between two legitimate peers in the presence of an external eavesdropper is studied from a physical-layer security perspective in the context of free-space optical (FSO) communications.

Directional-modulation-enabled physical-layer wireless security [PDF]

, 2017
Directional modulation (DM), as a promising keyless physical-layer security technique, has rapidly developed within the last decade. This technique is able to directly secure wireless communications in the physical layer by virtue of the property of its direction-dependent signal-modulation-formatted transmission.

Analysis of short blocklength codes for secrecy

EURASIP Journal on Wireless Communications and Networking, 2018
In this paper, we provide secrecy metrics applicable to physical-layer coding techniques with finite blocklengths over Gaussian and fading wiretap channel models and analyze their secrecy performance over several cases of concatenated code designs.

Physical Layer Security in Random NOMA-Enabled Heterogeneous Networks

IEEE Open Journal of the Communications Society
The performance of physical layer secrecy approach in non-orthogonal multiple access (NOMA)-enabled heterogeneous networks (HetNets) is analyzed in this paper. A K-tier multi-cell HetNet is considered, comprising NOMA adopted in all tiers.
