Security has become the primary concern in many telecommunications industries today as
risks can have high consequences. Especially, as the core and enable technologies will be …

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 …

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 …

Non-orthogonal multiple access (NOMA) is an essential enabling technology for the fifth-
generation (5G) wireless networks to meet the heterogeneous demands on low latency, high …

Abstract Power Domain Non-Orthogonal Multiple Access (PD-NOMA) is a potential
technology for the next generation of cellular networks. Compared to classical orthogonal …

Mobile edge computing (MEC) has been envisaged as a promising technique in the next-
generation wireless networks. In order to improve the security of computation tasks …

Nonorthogonal multiple access (NOMA) assisted semi-grant-free transmission admits grant-
free users to access the channels otherwise solely occupied by grant-based users, and has …

Cognitive radio (CR) and non-orthogonal multiple access (NOMA) have been deemed two
promising technologies due to their potential to achieve high spectral efficiency and massive …

In this correspondence, we investigate the physical layer security for cooperative
nonorthogonal multiple access (NOMA) systems, where both amplify-and-forward (AF) 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 …
