On secrecy analysis of wireless-powered relaying FSO-RF systems
, 2021 We investigate the physical-layer security performance for a wireless-powered relaying mixed free-space optical-radio frequency (FSO-RF) system. In this system, a source transmits optical information to a relay (R), which decodes the received signal with

Performance Analysis of Secret Precoding-Aided Spatial Modulation With Finite-Alphabet Signaling
IEEE Access, 2018 The precoding-aided spatial modulation (PSM) is first characterized with respect to its secrecy performance, which shows that the PSM is a secrecy embedded communication scheme when operated in the time-division duplex mode, but experiences security risk

Physical Layer Security of WPCNs With Imperfect CSI and Full-Duplex Receiver Aided Jamming
IEEE Access, 2019 In this paper, we investigate the secrecy performance of wireless powered communication networks (WPCNs) faced by multiple passive eavesdroppers, where the full-duplex (FD) receiver utilizes the harvested energy to send the artificial jamming for ...

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
