With the increasing demand for security in many sectors, such as defense and health
systems, developing secure Internet of Things (IoT) networks is a matter of great urgency …

Aiming at high energy consumption and information security problem in the simultaneous
wireless information and power transfer (SWIPT) multi-user wiretap network, we propose a …

A secure downlink transmission system which is exposed to multiple eavesdroppers and is
appropriate for Internet of Things (IoT) applications is considered. A worst case scenario is …

This paper investigates physical layer security (PLS) of uplink non-orthogonal multiple
access (NOMA) in Internet of Things (IoT) networks, where two devices transmit secret …

In this paper, we present a physical-layer security scheme that exploits artificial noise (AN) to
