Secrecy Capacity and Efficiency Outage Analysis of Cooperative PHY-Secure Wireless Systems and Secrecy Capacity-Based RIS Design

IEEE Access
Physical layer (PHY) security (PLS) leverages the inherent randomness of wireless fading channels to provide enhanced secrecy capacity. In this work, we consider a four-node, dual hop, eavesdropper-aware cooperative PHY-security model.

Software-Defined Radio Implementation of Two Physical Layer Security Techniques

, 2018
This thesis discusses the design of two Physical Layer Security (PLS) techniques on Software Defined Radios (SDRs). PLS is a classification of security methods that take advantage of physical properties in the waveform or channel to secure communication.

Physical Layer Security Beamforming Design via Deep Unfolding

Physical layer security (PLS) relies on avoiding attacks from a physical layer perspective. Beamforming has shown to be an effective alternative for this purpose, allowing the concentration of the resources in the legitimate user. This paper investigates
