Professor Tek Tjing LIE
Title: Electricity Utility and Grid of the Future: Implementation, Technology, Regulations and Policy
The interconnection between all energy-related ‘things’ within a grid, and even between the grids themselves in the Energy Internet, is both technologically complex and risky. It poses significant challenges for decision makers and regulators. It is imperative to investigate solutions for managing the risks posed by fast-paced technology changes, volatility of global electricity prices, system over-frequency, and cyber-physical threats.
Professor Tek Tjing LIE received his Bachelor degree in Electrical Engineering from Oklahoma State University, USA in 1986. He also received his Master of Science and Ph. D. degrees in Electrical Engineering from Michigan State University, USA in 1988 and 1992 respectively.
Professor Lie is the Deputy Head of School of Engineering, Computer and Mathematical Sciences, Auckland University of Technology, New Zealand. His research interests include power system control and operation, deregulated power systems, smart grids and renewable energy systems. He has authored/co-authored more than 180 journal and international conference papers.
Professor Soung Chang Liew
Soung received his S.B., S.M., E.E., and Ph.D. degrees from the Massachusetts Institute of Technology. From 1984 to 1988, he was at the MIT Laboratory for Information and Decision Systems, where he investigated Fiber-Optic Communications Networks. From March 1988 to July 1993, he was at Bellcore (now Telcordia), New Jersey, where he engaged in Broadband Network Research. He has been a Professor at the Department of Information Engineering, the Chinese University of Hong Kong (CUHK), since 1993. Prof. Liew is currently the Division Head of the Department of Information Engineering and a Co-Director of the Institute of Network Coding at CUHK. He is also an Adjunct Professor of Peking University and Southeast University, China.
Prof. Liew’s research interests include wireless networks, Internet of Things, intelligent transport systems, Internet protocols, multimedia communications, and packet switch design. Prof. Liew’s research group won the best paper awards in IEEE MASS 2004 and IEEE WLN 2004. Separately, TCP Veno, a version of TCP to improve its performance over wireless networks proposed by Prof. Liew’s research group, has been incorporated into a recent release of Linux OS. In addition, Prof. Liew initiated and built the first inter-university ATM network testbed in Hong Kong in 1993. Prof. Liew’s research group pioneered and advanced the development of Physical-layer Network Coding (PNC). The original paper on PNC was selected by Google Scholar as one of the ten “Classis Papers” in the field of Computer Networks and Wireless Communications in 2017.
Besides academic activities, Prof. Liew is active in the industry. He co-founded two technology start-ups in Internet Software and has been serving as a consultant to many companies and industrial organizations.
Prof. Liew is the holder of 12 U.S. patents and a Fellow of IEEE, IET and HKIE. He is the recipient of the first Vice-Chancellor Exemplary Teaching Award in 2000 and the Research Excellence Award in 2013 at the Chinese University of Hong Kong.

Efficient and Secure Authentication Schemes for IEEE 802.11ah Networks
IEEE 802.11ah, a specification belonging to 802.11 wireless local area network (WLAN) protocol family, has been recently released to support the long-range, low-power and low-rate wireless communication among smart devices used in Internet of Thing (IoT) systems. However, security requirements of the energy-constrained devices have plenty of issues different from the traditional wireless devices. It requires that the lightweight security protocols have to support low-power and low-latency as well as the long-lasting features of quantities of IoT devices. The recently released IEEE statndard, IEEE 802.11ai has specified a Fast Initial Link Setup (FILS), which is a brand-new approach aiming at establishing fast, stable and secure links among smart devices. IEEE 802.11ai could be applied to other wireless systems, such as the wireless system of IEEE 802.11ah with security enhancements. In this talk, I would address the secureity issues of IEEE 802.11ai and IEEE 802.11ah with an new proposal to enhance the authentication process in the link setup procedure specified by IEEE 802.11ai.
