On the Secrecy Performance of SWIPT Receiver Architectures with Multiple Eavesdroppers [PDF]
Wireless Communications and Mobile Computing, 2018 Physical layer security (PLS) has been shown to hold promise as a new paradigm for securing wireless links. In contrast with the conventional cryptographic techniques, PLS methods exploit the random fading in wireless channels to provide link security.

On Optimizing the Secrecy Performance of RIS-Assisted Cooperative Networks [PDF]
2020 IEEE 92nd Vehicular Technology Conference (VTC2020-Fall), 2020 Employing reconfigurable intelligent surfaces (RIS) is emerging as a game-changer candidate, thanks to their unique capabilities in improving the power efficiency and supporting the ubiquity of future wireless communication systems. Conventionally, a wireless network design has been limited to the communicating end points, i.e., the transmitter and the

Secrecy performance analysis over cascaded fading channels [PDF]
IET Communications, 2019 In this study, the authors investigate the secrecy performance at the physical layer of wireless communication systems where the channels are modelled as cascaded fading channels, in which the fading effects are worse than those in the cellular communication channels like Rayleigh and Nakagami‐ m
