Due to the broadcast nature of radio propagation, the wireless air interface is open and
accessible to both authorized and illegitimate users. This completely differs from a wired …

Physical layer security (PHY-security) takes the advantages of channel randomness nature
of transmission media to achieve communication confidentiality and authentication. Wiretap …

This article considers an artificial noise (AN)-aided secure MIMO wireless communication
system. To enhance the system security performance, the advanced intelligent reflecting …

This paper investigates the physical layer security of non-orthogonal multiple access
(NOMA) in large-scale networks with invoking stochastic geometry. Both single-antenna and …

As a complement to high-layer encryption techniques, physical layer security has been
widely recognized as a promising way to enhance wireless security by exploiting the …

The industrial environment poses strict requirements to the infrastructure of good and
service production and delivery. Communications are not an exception. Wired systems …

The dual use of radio signal for simultaneous wireless information and power transfer
(SWIPT) has recently drawn significant attention. To meet the practical requirement that the …

In this paper, we consider physical layer security provisioning in multicell massive multiple-
input-multiple-output (MIMO) systems. Specifically, we consider secure downlink …

In this paper, we investigate secure and reliable transmission strategies for multi-cell multi-
user massive multiple-input multiple-output systems with a multi-antenna active …

The heterogeneous cellular network (HCN) is a promising approach to the deployment of 5G
cellular networks. This paper comprehensively studies physical layer security in a multitier …
