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 paper, we study secure transmission designs for underlay cognitive radio networks in
the present of randomly distributed eavesdroppers. We consider the scenario where a …

The authors study the secure transmission design in random cognitive radio networks where
the primary users, the secondary users and the eavesdroppers are randomly distributed …

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) …

Cognitive radio has emerged as an essential recipe for future high-capacity, high-coverage
multitier hierarchical networks. Securing data transmission in these networks is of the utmost …

This letter investigates secure communications against eavesdropping in an underlay
cognitive radio network. The secondary users do not know the interference level that they …

Herein, we consider an underlay cognitive radio network (CRN) where mobile secondary
user wishes to transmit a confidential information to the secondary destination in the …

In this paper, we analyze the secrecy performance of multi-antenna cognitive wiretap
network, where the secondary transmitter (Alice) communicates with the secondary receiver …

In this paper, we investigate the secrecy performance of a multiantenna cognitive wiretap
network, where the secondary transmitter (Alice) communicates with the secondary receiver …

Wireless communication systems are vulnerable to eavesdropping attack in which the
attacker overhear the transmitted data in the network. Hence, the physical-layer security is of …
