Cooperation Diversity for Secrecy Enhancement in Cognitive Relay Wiretap Network Over Correlated Fading Channels

open access: yesIEEE Access, 2018
In this paper, we investigate the secrecy performance of dual-hop randomize-and-forward (RaF) cognitive relay multi-channel wiretap networks over correlated fading channels, in which the eavesdropper can wiretap the information from source and relays ...

On secrecy analysis of wireless-powered relaying FSO-RF systems

open access: yes, 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

open access: yesIEEE 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

Addressing Structural Secrecy as a Way of Nurturing Resilient Performance

open access: yes, 2021
Structural secrecy refers to a systematic undermining of attempts to know and interpret situations in organisations, which significantly challenges their abilities to perform resiliently.

Physical Layer Security of WPCNs With Imperfect CSI and Full-Duplex Receiver Aided Jamming

open access: yesIEEE 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]

open access: yes2020 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
