Bio:

Tolga M. Duman is a Professor of Electrical and Electronics Engineering Department at Bilkent University in Turkey. He received the B.S. degree from the same university in 1993, M.S. and Ph.D. degrees from Northeastern University, Boston, MA, in 1995 and 1998, respectively, all in electrical engineering. Prior to joining Bilkent University in September 2012, he has been a Professor with the Electrical Engineering Department of Arizona State University for about fifteen years. Dr. Duman’s current research interests are in systems, with particular focus on communications and signal processing, including wireless and mobile communications, coding/modulation, coding for wireless communications, data storage systems and underwater acoustic communications.

Dr. Duman is a Fellow of IEEE, a recipient of the National Science Foundation CAREER Award and IEEE Third Millennium medal. He has served as an editor for various journals and took part in many conference organization activities. He is currently the coding and information theory area editor of IEEE Trans. on Communications and the Editor-in-Chief of Elsevier’s Physical Communication, and he is the TPC co-chair of IEEE PIMRC 2019.

Abstract:

Providing secure communications over the physical layer with the objective of achieving secrecy without requiring a secret key has been receiving growing attention within the past decade. The majority of the existing studies in this area are from an information theoretical perspective. In this talk, we review the recent advances on physical layer security for use in wireless communication systems with a particular focus on its practical aspects. Specifically, we explore transmission techniques that use finite alphabet signaling as opposed to Gaussian inputs (which are not realizable). We explore transmit signal design algorithms for single-antenna as well as multi-antenna wiretap channels under different assumptions on the channel state information at the transmitter. Moreover, we present a review of the recent results on secure transmission with discrete signaling for various scenarios including multi-carrier transmission systems, broadcast channels with confidential messages, cognitive multiple access and relay networks. We also present an overview of practical code construction approaches for physical layer security and discuss related open problems.  Finally, we go over promising future research directions both on physical layer security and other related areas that are gaining importance including data privacy.
