Modern communication systems need to satisfy pre-specified requirements on spectral
efficiency and security. Physical layer security is a concept that unifies both and connects …

With the fast development of commercial unmanned aerial vehicle (UAV) technology, there
are increasing research interests on UAV communications. In this work, the mobility and …

This study proposes an intensity modulation/direct detection intermediate frequency-over-
fiber (IFoF) system that generates a microwave orthogonal frequency-division multiplexing …

Passively overheard massive multiple-input multiple-output (MIMO) settings are capable of
suppressing eavesdroppers via narrow beamforming towards legitimate receivers. This …

With the growing popularity of wearable devices, body-centric networks have become the
focus of Internet of Things (IoT) research. However, malicious eavesdroppers and attackers …

In this paper, we investigate the physical layer security of a non-orthogonal multiple access
(NOMA) based downlink hybrid satellite-terrestrial relay network where the satellite …

This paper studies a single UAV-enabled secure data dissemination system, in which the
UAV is employed as an aerial base station to secretly communicate with multiple ground …

We propose a secure user pairing (UP) and power allocation (PA) strategy for a downlink
Non-Orthogonal Multiple Access (NOMA) system when there exists an external …

In this paper, we propose a novel antenna selection scheme to enhance the secrecy
performance in a relay-aided non-orthogonal multiple access (NOMA) network against an …

In this paper, an analysis of an input distribution that achieves the secrecy capacity of a
general degraded additive noise wiretap channel is presented. In particular, using convex …
