"Physical Layer Security in Wireless Networks"

H. Vincent Poor
Dean of the School of Engineering and Applied Science
Princeton University


Security in wireless networks has traditionally been considered to be an issue to be addressed at the higher layers of the network. However, with the emergence of ad hoc and other less centralized networking architectures, there has been an increase in interest in the potential of the wireless physical layer to provide communications security. Information theory provides a natural framework for the study of this issue, and consequently there has been a resurgence of interest in informationtheoretic security in recent years, particularly for wireless channel models. This talk will describe basic concepts and recent work in this area. In particular, new results for security in wireless multi-user channels – i.e., broadcast, multiple-access and interference channels - will be described. The modeling of quantum multi-user channels will also be discussed, with a view toward stimulating interest in physical layer security in this context.
