Security- and Reliability-Guaranteed Transmission Control of Time-Sensitive Physical Layer Security Systems [PDF]
Entropy, 2023 In this paper, we consider information transmission over a three-node physical layer security system. Based on the imperfect estimations of the main channel and the eavesdropping channel, we propose reducing the outage probability and interception ...

Quantum Security for the Physical Layer [PDF]
IEEE Communications Magazine, 2013 The physical layer describes how communication signals are encoded and transmitted across a channel. Physical security often requires either restricting access to the channel or performing periodic manual inspections.

Physical Layer Security Using Two-Path Successive Relaying [PDF]
Sensors, 2016 Relaying is one of the useful techniques to enhance wireless physical-layer security. Existing literature shows that employing full-duplex relay instead of conventional half-duplex relay improves secrecy capacity and secrecy outage probability, but this ...

UAV Swarm-Enabled Aerial CoMP: A Physical Layer Security Perspective [PDF]
IEEE Access, 2019 Unlike aerial base station enabled by a single unmanned aerial vehicle (UAV), aerial coordinated multiple points (CoMP) can be enabled by a UAV swarm. In this case, the management of multiple UAVs is important.
