Title: Exploiting Information Asymmetry in Dynamic Games

Abstract: Due to the assumed intelligence and learning capabilities on both the attacker and defender in modern systems and networks, the competition between them will necessarily be an arms race. Such intelligent and dynamic interactions can be modeled as stochastic games, and multi-agent reinforcement learning can be employed to explore the optimal strategies for both parties. There are many challenges in this field, as well as opportunities.  Recently we have investigated how the information asymmetry between two parties may be exploited to gain advantage over the opponent. Our approach is illustrated through applications in cognitive radio networks and energy harvesting systems under malicious attacks.

Bio: Huaiyu Dai (M’03, SM’09) received the B.E. and M.S. degrees in electrical engineering from Tsinghua University, Beijing, China, in 1996 and 1998, respectively, and the Ph.D. degree in electrical engineering from Princeton University, Princeton, NJ in 2002.

He was with Bell Labs, Lucent Technologies, Holmdel, NJ, during summer 2000, and with AT&T Labs-Research, Middletown, NJ, during summer 2001. Currently he is an Associate Professor of Electrical and Computer Engineering at NC State University, Raleigh. His research interests are in the general areas of communication systems and networks, advanced signal processing for digital communications, and communication theory and information theory. His current research focuses on networked information processingand crosslayer design in wireless networks,cognitive radio networks, wireless security, and associated information-theoretic and computation-theoretic analysis.

He has served as an editor of IEEE Transactions on Communications, Signal Processing, and Wireless Communications. He co-edited two special issues of EURASIP journalson distributed signal processing techniquesfor wireless sensor networks, and on multiuserinformation theory and related applications, respectively. He co-chairs the Signal Processing for Communications Symposium of IEEE Globecom 2013, the Communications Theory Symposium of IEEE ICC 2014, and the Wireless Communications Symposium of IEEE Globecom 2014.
