Due to the malicious attacks in wireless networks, physical layer security has attracted
increasing concerns from both academia and industry. The research on physical layer …

This paper proposes a new design of non-orthogonal multiple access (NOMA) under
secrecy considerations. We focus on a NOMA system, where a transmitter sends confidential …

In this paper, we study physical layer security for the downlink of cellular networks, where
the confidential messages transmitted to each mobile user can be eavesdropped by both; 1) …

In this paper, we investigate the interactions between a base station (BS) and a full-duplex
(FD) active eavesdropper in the uplink of multi-cell massive multiple-input multiple-output …

We design a new relay-aided secure transmission scheme, in which a source communicates
with a destination through a trusted decode-and-forward relay in the presence of spatially …

We propose a new location-based beamforming (LBB) scheme for wiretap channels, where
a multi-antenna source communicates with a single-antenna legitimate receiver in the …

We investigate the optimality and power allocation algorithm of beam domain transmission
for single-cell massive multiple-input multiple-output (MIMO) systems with a multi-antenna …

We investigate signaling and linear precoding designs for secure downlink communications
in a multiuser MIMO (MU-MIMO) network. The network is tapped by an external …

Physical layer security is a promising way to secure the wireless communications in the
Internet of Things (IoT). Motivated by the fact that the limited feedback resources in the IoT …

In this paper, we consider the problem of resource allocation in the orthogonal frequency
division multiple access system with single source and M untrusted users in presence of a …
