Quantum security for the physical layer [PDF]
IEEE Communications Magazine, 2013 The physical layer describes how communication signals are encoded and transmitted across a channel. Physical security often requires either restricting access to the channel or performing periodic manual inspections. In this tutorial, we describe how the field of quantum communication offers new techniques for securing the physical layer.

Secure physical layer network coding versus secure network coding [PDF]
2018 IEEE Information Theory Workshop (ITW), 2018 When a network has relay nodes, there is a risk that a part of the information is leaked to an untrusted relay. Secure network coding (secure NC) is known as a method to resolve this problem, which enables the secrecy of the message when the message is transmitted over a noiseless network and a part of the edges or a part of the intermediate (untrusted)

Physical Layer Security through Secure Channel Estimation
2018 IEEE 87th Vehicular Technology Conference (VTC Spring), 2018 The random nature of wireless channel can be utilized to achieve secure communications. Recently, there have been some contributions towards finding practical approaches to provide physical layer security, but robust and secure channel estimates are critical in achieving secrecy.

Cooperative jamming for wireless physical layer security [PDF]
2009 IEEE/SP 15th Workshop on Statistical Signal Processing, 2009 Cooperative jamming is an approach that has been recently proposed for improving physical layer based security for wireless networks in the presence of an eavesdropper. While the source transmits its message to its destination, a relay node transmits a jamming signal to create interference at the eavesdropper.
