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 ...

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 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 ...

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 Analysis of Wireless Sensor Networks [PDF]
IEEE Sensors Letters, 2019 The wireless sensor network (WSN) plays a fundamentally important role in the realization of Internet of Things and Industry 4.0. In this article, we study the physical layer security performance of a large-scale ad hoc and homogeneous WSN. To accurately evaluate the secrecy performance of the large-scale WSN, we take into account the randomness of the

Secrecy Performance of Mobile Image Transmission Networks [PDF]
Proceedings of the 11th EAI International Conference on Mobile Multimedia Communications, 2018 Due to the user mobility, the physical layer security of mobile image transmission networks is an important challenging task.In this paper, based on the classic Wyner wiretap model, the secrecy performance of mobile image transmission networks is investigated. We derive exact closed-form expressions for the average secrecy capacity (ASC).
