A key feature of the non-orthogonal multiple access (NOMA) technique is that users with
better channel conditions have prior information about the messages of other users. The …

The secrecy outage probability (SOP) performance is investigated for a cooperative non-
orthogonal multiple access system under eavesdropping attack, where a base station …

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 …

In this paper, a novel approach is introduced to study the achievable delay-guaranteed
secrecy rate, by introducing the concept of the effective secrecy rate (ESR). This study …

This paper investigates the covert communication of cooperative non-orthogonal multiple
access (NOMA) systems, where the near user serves as a decode-and-forward (DF) relay …

In this paper, we investigate the secrecy performance of an unmanned aerial vehicle (UAV)-
based full-duplex (FD) relay non-orthogonal multiple access (NOMA) system over the …

In this paper, we investigate joint jammer selection and network coding for secrecy
enhancement under transceiver hardware impairment. We propose two protocols of joint …

We have proposed and analyzed secrecy performance of a network architecture which
contains a source, two destinations, a friendly jammer (FJ) and an eavesdropper (Eve). To …

In this paper, we evaluate system performances of a multi-hop relay protocol with presence
of an active eavesdropper. In the proposed protocol, a source attempts to transmit its data to …
