This paper studies the physical layer security (PLS) in an underlay cognitive radio (CR)
network. Under an interference constraint set by the primary user, we propose a secure …

In this letter, physical layer (PHY) security is investigated for both primary and secondary
transmissions of a cognitive radio network (CRN) that is in danger of malicious attempt by an …

In this paper, the benefit of distinguishable diversity order within a co-operative relay system
is exploited to overcome the problem of secure communication in an underlay wiretap …

In this paper, we investigate the secrecy outage probability in a dual-hop decode-and-
forward (DF) secondary cognitive radio network, which is equipped with one source, one …

This paper investigates the secrecy performance of an underlay cooperative cognitive
relaying network, wherein a secondary source vehicle communicates with a fixed secondary …

In this paper, a game theory-based cooperation scheme is investigated to enhance the
physical layer security in both primary and secondary transmissions of a cognitive radio …

Security is a challenging issue for cognitive radio (CR) to be used in future 5G mobile
systems. Conventionally, interference will degrade the performance of a primary user (PU) …

In this letter, the secrecy performance in cognitive radio networks (CRNs) over fluctuating
two-ray (FTR) channels, which is used to model the milimeter wave channel, is investigated …

In this paper, we introduce a new cooperative paradigm for secure communication in
cognitive radio networks (CRNs) where secondary users (SUs) are allowed to access the …

In this paper, the secrecy outage performance of an underlay cognitive decode-and-forward
relay network over independent but not necessarily identical distributed Nakagami-m fading …
