In this paper, we address the physical-layer security issue of a secondary user (SU) in a
spectrum-sharing cognitive radio network (CRN) from an information-theoretic perspective …

In this letter, we consider an underlay cognitive radio network in which a secondary
transmitter (ST) communicates with a secondary destination (SD) with the aid of multiple …

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 …

This paper investigates the physical layer security problem of cognitive decode-and-forward
relay networks over Nakagami-m fading channels. We consider the relaying communication …

This paper considers a multiple-input-multiple-output (MIMO) cognitive wiretap system over
Nakagami-m channels with generalized selection combining (GSC), where confidential …

This paper studies the achievable rates of the multi-antenna or multiple-input multiple-output
(MIMO) secrecy channel with multiple single-/multi-antenna eavesdroppers. By assuming …

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, a physical-layer-security scheme for an underlay relay-based cognitive radio
network (CRN) that uses orthogonal frequency-division multiplexing (OFDM) as the medium …

We consider an underlay cognitive radio system, in which a source in a secondary system
transmits information to a full-duplex (FD) wireless-powered destination node in the …

In this paper, we introduce transmit antenna selection/maximal-ratio combining (TAS/MRC)
scheme in dual-hop randomize-and-forward (RaF) cognitive multiple-input multiple-output …
