The dialogic performativity of secrecy and transparency
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 ...

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.

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.

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 Use of HAPS to Increase Secrecy Performance in Satellite Networks [PDF]
2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021 In this paper, we investigate the secrecy performance of radio frequency (RF) eavesdropping for a high altitude platform station (HAPS) aided satellite communication (SatCom) system. More precisely, we propose a new SatCom scheme where a HAPS node is used as an intermediate relay to transmit the satellite's signal to the ground station (GS).

On Secrecy Performance of Mixed THz-FSO Relaying System
2023 IEEE Conference on Standards for Communications and Networking (CSCN), 2023 <p>Terahertz (THz) frequency band and free-space optical (FSO) communication can be proven potential solutions to the spectrum scarcity challenges in the emerging applications in the 6G. In this direction, a mixed THz-FSO relaying system is proposed in this paper.
