Secrecy Performance Analysis of Two-Way Relay Non-Orthogonal Multiple Access Systems
IEEE Access, 2020 This paper studies physical layer security for two-way relay non-orthogonal multiple access systems. Specifically, by employing a decode-and-forward relay and considering both the maximum-ratio combining and selection combining schemes at the ...

Secrecy Outage Probability of SWIPT-OFDMA Schemes with Transmit Antenna Selection
2023 31st Signal Processing and Communications Applications Conference (SIU), 2023 This study examines the wireless communications secrecy performance of multi-user (MU) simultaneous wireless information and power transfer (SWIPT) scheme employing transmit antenna selection (TAS) and maximal-ratio combining (MRC). In order to address the user scheduling requirement of MU-SWIPT scheme, orthogonal frequency-division multiple access ...

Secure Transmission for Relay Wiretap Channels in the Presence of Spatially Random Eavesdroppers [PDF]
, 2015 We propose a secure transmission scheme for a relay wiretap channel, where a source communicates with a destination via a decode-and-forward relay in the presence of spatially random-distributed eavesdroppers.

Hybrid Cache Placement for Physical-Layer Security in Cooperative Networks
IEEE Access, 2018 Due to the broadcast nature of wireless transmission, traditional wireless two-hop relaying is vulnerable for eavesdroppers to overhear messages. In order to enhance the physical-layer security, this paper studies one cooperative network with caching ...

Secrecy outage probability of inter‐vehicular cognitive radio networks
International Journal of Communication Systems, 2019 SummaryHerein, we consider an underlay cognitive radio network (CRN) where mobile secondary user wishes to transmit a confidential information to the secondary destination in the presence of an illegitimate eavesdropper which is trying to steal the classified message signal.

On Secrecy Outage Probability and Average Secrecy Rate of Large‐Scale Cellular Networks
Wireless Communications and Mobile Computing, 2018 We investigate the secrecy performance in large‐scale cellular networks, where both Base Stations (BSs) and eavesdroppers follow independent and different homogeneous Poisson point processes (PPPs). Based on the distances between the BS and user, the intended user selects the nearest BS as serving BS to transmit the confidential information.

Rate Splitting in the Presence of Untrusted Users: Outage and Secrecy Outage Performances
IEEE Open Journal of the Communications Society, 2022 In this contribution, a thorough investigation of the performance of rate splitting is conducted in terms of outage and secrecy outage for the simultaneous service to a near user and far user, where the latter attempts to overhear the message of the ...
