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

Internet of Things (IoT) is able to provide various physical objects to exchange their
information through the 6G wireless communication network. However, with the large …

We investigate a secrecy-enhancing design for cooperative downlink and uplink non-
orthogonal multiple access (NOMA) transmissions with an untrusted relay. A source uses the …

The broadcast nature of the wireless medium allows unintended users to eavesdrop on
confidential information transmission. In this regard, we investigate the problem of secure …

We propose a novel non-orthogonal multiple access (NOMA)-inspired jamming and relaying
scheme to enhance the physical layer security of untrusted relay networks. Particularly …

In this paper, a joint relay selection and power allocation (JRP) scheme is proposed to
enhance the physical layer security of a cooperative network, where a multiple antennas …

In this paper, we propose a two-way secure communication scheme where two transceivers
exchange confidential messages via a wireless-powered untrusted amplify-and-forward …

In this paper, we examine the secrecy performance of two-way relaying between a large-
scale multiple antenna base station (BS) and a single antenna mobile user (MU) in the …

In this paper, the security aspect of an amplify-and-forward relaying network with untrusted
relay nodes is considered. The untrusted nodes can help to forward the received signal and …

To improve the secrecy performance of the untrusted relay system with a multiple-antenna
destination, a novel full-duplex destination jamming scheme with optimal antenna selection …
