In this paper, we address the challenge of establishing secure communication within a
symbiotic radio (SR) network. This network comprises a primary transmitter (PT), a primary …

This paper investigates the secrecy performance of a single-input multiple-output (SIMO)
based underlay cognitive radio networks. In particular, a single-antenna secondary …

By taking a variety of realistic hardware imperfections into consideration, we propose an
optimal power allocation (OPA) strategy to maximize the instantaneous secrecy rate of a …

This paper investigates the ergodic achievable secrecy rate (EASR) of multiple-antenna
amplify-and-forward relay systems, where one eavesdropper can wiretap the relay. To …

We investigate the spectrum sharing possibility as an incentive to enhance the physical
layer security. The concept behind is that a legitimate source-destination pair …

We investigate a relay network where the source can potentially utilize an untrusted non-
regenerative relay to augment its direct transmission of a confidential message to the …

In this paper, we investigate the secrecy performance of a Cooperative Cognitive Radio
Network (CCRN) in the presence of an eavesdropper (EAV). The secondary users (SUs) are …

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 …

This work explores the physical layer security of an underlay cognitive radio network (CRN)
in the presence of a powerful interferer called a primary transmitter (PT) under peak …

In this paper, the impacts of unreliable backhaul links on the secrecy performance of
cooperative single carrier heterogeneous networks in the presence of eavesdroppers are …
