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 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 ...

Secrecy Outage Probability of Network-Coded Cooperative Communication
CoRR, 2014 We evaluate the secrecy performance of a multiple access cooperative network where the destination node is wiretapped by a malicious and passive eavesdropper. We propose the application of the network coding technique as an alternative to increase the secrecy at the destination node, on the top of improving the error performance of the legitimate ...

Secrecy Outage Probability: Revisited.
CoRR, 2022 This paper technically explores the secrecy rate $Λ$ and a maximisation problem over the concave version of the secrecy outage probability (SOP) as $\mathop{{\rm \mathbb{M}ax}}\limits_{Δ} {\rm \; } \mathbb{P}\mathscr{r} \big( Λ\ge λ\big) $. We do this from a generic viewpoint even though we use a traditional Wyner's wiretap channel for our system model
