On the Security of Cognitive Radio Networks [PDF]
IEEE Transactions on Vehicular Technology, 2015 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 importance. In this paper, we consider the cognitive wiretap channel and propose multiple antennas to secure the transmission at the physical layer, where the ...
