Realistic Secrecy Performance Analysis for LiFi Systems [PDF]
IEEE Access, 2021 This paper studies the secrecy performance of light-fidelity (LiFi) networks under the consideration of random device orientation and partial knowledge of the eavesdroppers’ channel state information. Particularly, the secrecy capacity and secrecy

Secrecy Performance Analysis of Cooperative Multihop Transmission for WSNs under Eavesdropping Attacks [PDF]
Sensors, 2023 Multihop transmission is one of the important techniques to overcome the transmission coverage of each node in wireless sensor networks (WSNs). However, multihop transmission has a security issue due to the nature of a wireless medium.

On secrecy performance of industrial Internet of things [PDF]
Internet Technology Letters, 2018 Physical layer security has been shown to hold promise as a new paradigm for securing wireless links. This paper provides secrecy performance analysis for industrial Internet of things, where a set of industrial devices communicates in the presence of eavesdropper under a Weibull fading environment. We derive a closed‐form expression for secrecy outage

Exploiting Secrecy Performance of Uplink NOMA in Cellular Networks [PDF]
IEEE Access, 2021 We study the secrecy transmission of uplink non-orthogonal multiple access (NOMA) with single antenna and multi-antenna users in presence of an eavesdropper. Two phases are required for communications during each time frame between the users and the base

Secrecy Performance of Correlated $\alpha$ -$\mu$ Fading Channels [PDF]
IEEE Communications Letters, 2019 This letter investigates the secrecy performance of the classical Wyner’s wiretap model, where the main channel and eavesdropper channel experience correlated $\alpha $ - $\mu $ fading. Novel and exact expressions for the average secrecy capacity and secrecy outage probability are derived for the considered realistic scenario.

On the Secrecy Performance of Land Mobile Satellite Communication Systems
IEEE Access, 2018 In this paper, we investigate the secrecy performance against eavesdropping of a land mobile satellite (LMS) system, where the satellite employs the spot beam technique, and both the terrestrial user and eavesdropper are equipped with multiple antennas and utilize maximal ratio combining to receive the confidential message.
