Physical layer security is an emerging technique to improve the wireless communication
security, which is widely regarded as a complement to cryptographic technologies. To …

In this paper, we study the secrecy problem for a relay-based vehicular network. We assume
that the legitimate transmitter, legitimate receiver, and eavesdropper are equipped with a …

In this paper, we consider a multi-hop decode-and-forward (DF) relaying transmission in
underlay cognitive radio networks. Considering the presence of an eavesdropper that …

In this paper, we study physical layer security in an underlay cognitive radio (CR) network.
We consider the problem of secure communication between a secondary transmitter …

In this study, the physical layer security for cognitive radio network (CRN) will be
investigated in which a secondary user transmitter (SU-Tx) sends confidential information to …

We look into adopting improper Gaussian signaling (IGS) in order to enhance the secrecy
performance of an underlay cognitive radio network since in interference-limited networks …

This letter addresses the physical layer security for an underlay cognitive radio sensor
network over α-μ fading channels, where α and μ denote the nonlinearity and clustering of …

This paper studies the secure multiple-antenna transmission in slow fading channels for the
cognitive radio network, where a multiple-input, single-output, multieavesdropper (MISOME) …

This paper investigates data transmission and physical-layer secrecy in cognitive radio (CR)
networks. We propose to apply full-duplex transmission and dual antenna selection at a …

This paper considers a single-input-multiple-output underlay cognitive wiretap system over
Nakagami-m channels with generalized selection combining, where confidential messages …
