Wireless physical layer security [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance Security is a very important issue in the design and use of wireless networks. Traditional methods of providing security in such networks are impractical for some emerging types of wireless networks due to the light computational abilities of some wireless devices [such as radio-frequency identification (RFID) tags ...

Techniques for Enhanced Physical-Layer Security [PDF]
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010 Information-theoretic security--widely accepted as the strictest notion of security--relies on channel coding techniques that exploit the inherent randomness of propagation channels to strengthen the security of communications systems. Within this paradigm, we explore strategies to improve secure connectivity in a wireless network.
