Secure Relay and Jammer Selection for Physical Layer Security [PDF]
IEEE Signal Processing Letters, 2015 Secure relay and jammer selection for physical-layer security is studied in a wireless network with multiple intermediate nodes and eavesdroppers, where each intermediate node either helps to forward messages as a relay, or broadcasts noise as a jammer.

Special issue on physical-layer security
Journal of Communications and Networks, 2012 The unprecedented development of wireless networks and increased concerns for their security have fostered a renewed interest for communication schemes that ensure confidentiality at the physical layer itself. The idea that there is security to be gained by harnessing the randomness of the physical-layer with appropriate coding schemes has now evolved ...

Location-Based Beamforming and Physical Layer Security in Rician Wiretap Channels
, 2016 We propose a new location-based beamforming (LBB) scheme for wiretap channels, where a multi-antenna source communicates with a single-antenna legitimate receiver in the presence of a multi-antenna eavesdropper.
