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.

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

Relay-Assisted Communications over Multi-Cluster Two-Wave Fading Channels [PDF]
SensorsThis paper examines the secrecy performance of a decode-and-forward (DF) relay-assisted device-to-device (D2D) communication system operating over Terahertz (THz) channels in multi-cluster two-wave (MTW) fading environments.

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 ...

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).
