Title: Security by the Physical Layer: A Promising Direction for Next Generation Wireless Network Design
Speaker: Prof. Aylin Yener (
Physical layer security aims to provide secure communication guarantees built in to the network design at its foundation. The promise of absolute data confidentiality is particularly relevant in the context of wireless systems operating in an open broadcast medium. Having its roots in existence results in information theory and incubated in the information theory community for close to a decade, wireless physical layer security research has grown to be a vibrant area in communications, information theory, coding theory and signal processing for communications. The richness of the research questions and the resulting new insights makes physical layer security a promising direction for next generation wireless systems. The current research effort has thus started to look at solutions towards bridging the gap from the theoretical constructs to more practically relevant communication scenarios.
In this talk we will provide an overview of the advancements since 2005, and the resulting design insights. These include insights related to inducing judicious interference for confidentiality, i.e. cooperative jamming, structured signaling, multiantenna signaling strategies and merits of feedback. We will then overview some of the more recent advancements towards relaxing some of the idealized assumptions in earlier problem constructs, notably the channel state information in multiantenna channels with secrecy constraints, as well as research efforts towards getting close to practical system design. We will conclude with remaining challenges and open problems in the area.
