… We consider the problem of secure communication between a secondary transmitter– … , we
design four transmission protocols to achieve the secure transmission in the CR network. We …

… To enhance the secure transmission of the secondary network, we propose a simple and
decentralised transmission scheme, which jointly incorporates the secrecy guard zone and …

… the secondary user (SU) by jointly designing the transmit BF at the CBS and reflect BF at the
IRS… As for the transmit BF at the CBS, we propose a heuristic robust transmit BF algorithm to …

… communication is required to connect and provide transmission, processing, recording and
… consider all these stages of security envisioned and facilitated by a cognitive radio network. …

… for secure transmission in a cognitive radio (CR) network. In particular, a neural network (NN…

… security (PLS) in an underlay cognitive radio (CR) network. Under an interference constraint
set by the primary user, we propose a secure transmission … of its power to transmit jamming …

… In this paper, we study secure transmission in CCRNs where energy harvesting enabled
SUs (may be selected as a relay or jammer) can assist PUs to improve the secrecy rate. For a …

… Securing data transmission in these networks is of the utmost importance. In this paper…
