Secrecy performance analysis of IRS-NOMA systems
EURASIP Journal on Wireless Communications and Networking, 2023 AbstractIn this paper, we propose to utilize an intelligent reflecting surface (IRS) as a promising technology to enhance the coverage and physical layer security of non-orthogonal multiple access (NOMA) system. In particular, an IRS-assisted NOMA system is considered with the aid of careful channel ordering of the NOMA users, in which the transmitter ...

Secrecy Performance of Wirelessly Powered Wiretap Channels [PDF]
IEEE Transactions on Communications, 2016 This paper considers a wirelessly powered wiretap channel, where an energy constrained multi-antenna information source, powered by a dedicated power beacon, communicates with a legitimate user in the presence of a passive eavesdropper. Based on a simple time-switching protocol, where power transfer and information transmission are separated in time ...

On the Secrecy Performance and Power Allocation in Relaying Networks With Untrusted Relay in the Partial Secrecy Regime [PDF]
IEEE Transactions on Information Forensics and Security, 2020 Recently, three useful secrecy metrics based on the partial secrecy regime were proposed to analyze secure transmissions on wireless systems over quasi-static fading channels, namely: generalized secrecy outage probability, average fractional equivocation, and average information leakage.

On the Secrecy Performance of Mixed RF/UOW Communication System [PDF]
2018 IEEE Globecom Workshops (GC Wkshps), 2018 In this paper, the secrecy performance of a dual-hop mixed radio-frequency/underwater optical wireless communication (RF/UOWC) system is investigated. The considered system consists of one single antenna source node ($S$) communicating with one destination node ($D$), considered as the legitimate receiver, through the help of one amplify-and-forward ...

The dialogic performativity of secrecy and transparency [PDF]
Human Relations, 2023 How does the pursuit of transparency and insight have a tendency to produce secrecy? And vice versa? In popular and political discourse, secrecy and transparency are usually depicted as mutually exclusive practices. At the same time, we know from extant research that the two are closely related, that they each have performative effects, and tend to ...

Secrecy performance of terahertz wireless links in rain and snow [PDF]
Nano Communication Networks, 2021 Wireless communication technique at terahertz (THz) frequencies is regarded as the most potential candidate for future wireless networks due to its wider frequency bandwidth and higher data capacity when compared to that employing radio frequency (RF) and millimeter wave (mmWave).

Improving Secrecy Performance of a Wirelessly Powered Network [PDF]
IEEE Transactions on Communications, 2017 This paper considers the secrecy communication of a wirelessly powered network, where an energy-constrained legitimate transmitter (Alice) sends message to a legitimate receiver (Bob) with the energy harvested from a dedicated power beacon, while an eavesdropper (Eve) intends to intercept the information.
