This paper investigates the joint impact of nodes' mobility and imperfect channel estimates
on the secrecy performance of an underlay cognitive radio vehicular network over Nakagami …

This paper examines the secrecy performance of reconfigurable intelligent surface aided
wireless communication systems. Specifically, we derive the secrecy outage probability …

This paper considers a single-input-multiple-output non-orthogonal multiple access enabled
vehicular communication system, and investigates its secrecy performance over time …

In this paper, we investigate the joint impact of nodes mobility and imperfect channel
estimates on the secrecy performance of a cognitive vehicular radio network under time …

In massive multiple-input multiple-output (MIMO) systems, a multi-antenna eavesdropper
could potentially harm the uplink security by channel estimation in the training phase and …

In a wiretap channel system model, the jammer node adopts the energy-harvesting signal as
artificial noise (jamming signal) against the cooperative eavesdroppers. There are two …

This work considers a time-varying Rayleigh block fading broadcast channel formed by two
users and an eavesdropper, external to the legitimate network. One of the users is the …

This article is focused on implementing simultaneous wireless information and power
transmission as a physical layer security measure by using artificial noise. A series of high …

This paper presents an efficient scheme to increase the physical layer security of
OFDM/OQAM wireless communication systems in the presence of eavesdroppers. This …

This work addresses the security of a two-user broadcast channel. The challenge of
protecting a broadcast channel is associated with the necessity of securing the system, not …
