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. In this tutorial, we describe how the field of quantum communication offers new techniques for securing the physical layer.

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 ...

A survey on OFDM physical layer security [PDF]

Physical Communication, 2019
Abstract Physical Layer Security (PLS) is an emerging paradigm employed to enhance wireless network security without relying on higher-layer encryption techniques. PLS enables legitimate users to exchange confidential messages over a wireless medium in the presence of adversaries, by utilizing the main properties and characteristics of the wireless ...
