Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …

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 …

Driven by the rapid escalation of the wireless capacity requirements imposed by advanced
multimedia applications (eg, ultrahigh-definition video, virtual reality, etc.), as well as the …

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 …

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 …

Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

This paper quantifies the impact of correlated fading on secure communication of multiple
amplify-and-forward (AF) relaying networks. In such a network, the base station (BS) is …

In this paper, the physical layer security of applying non-orthogonal multiple access (NOMA)
in large-scale networks is investigated. In the considered scenario, both the NOMA users …

This paper considers a multiple-input-multiple-output (MIMO) cognitive wiretap system over
Nakagami-m channels with generalized selection combining (GSC), where confidential …
