Enhancing information security has become increasingly significant in the digital age. This
paper investigates the concept of physical layer security (PLS) within a relay-aided power …

Despite providing a wired communications infrastructure, power line communication (PLC)
is broadcast in nature due to the shared channel usage by all intended users. This …

In this paper, we consider a legitimate proactive eavesdropping scenario where a distant
central monitor covertly wiretaps the communication between a pair of suspicious users via …

In underground mines, physical layer security (PLS) technology is a promising method for
the effective and secure communication to monitor the mining process. Therefore, in this …

With the emergence of advanced communication technologies such as infrastructure-free
communication networks, the need for proactive eavesdropping which can constantly …

We study a relay and user selection scheme to improve the secrecy performance of
cooperative multi-user multiple amplify-and-forward (AF) relay network. Nevertheless, relay …

In this study, security schemes at the physical layer are proposed for an amplify‐and‐
forward relay system in the presence of a passive eavesdropper. We focus on maximising …

In this article, a new relay-aided secure communication system is investigated, where a
transmitter sends signals to a destination via an amplify-and-forward (AF) relay in the …

This paper studies the use of multi-antenna harvest-and-jam (HJ) helpers in a multi-antenna
amplify-and-forward (AF) relay wiretap channel assuming that the direct link between the …

This letter studies the proactive eavesdropping in a suspicious decode-and-forward relay
system, where the suspicious communication is divided into transmitter-to-relay (ST-SR) …
