Security Games for the Smart Grid
- 11:00 15th November 2012 ( week 6, Michaelmas Term 2012 )Christopher Strachey Room of the Robert Hooke Building
The power grid, on which most economic activities rely, is a critical infrastructure that must be protected against potential threats. Advanced monitoring technologies at the center of the smart grid evolution increase its efficiency but also make it more susceptible to malicious attacks such as false data injection. This talk is about the development of a game-theoretic approach to smart grid security by combining quantitative risk management with decision making on protective measures. Specifically, the consequences of data injection attacks are quantified using a risk assessment process based on simulations. Then, the quantified risks are used as an input to a stochastic game model, where the decisions on defensive measures are made taking into account resource constraints. Security games provide the framework for choosing the best response strategies against attackers in order to minimize potential risks. The theoretical results obtained are demonstrated using numerical examples.
Speaker bio
Yee Wei Law received his BEng from University of Southampton, MEng from Nanyang Technological University, and PhD from University of Twente. Till now, Dr Law has 6.5 years of postdoctoral experience from the IT security industry and The University of Melbourne. His research interests cover a broad spectrum, ranging from networked virtual environments (1999-2001), digital rights management (2001-2003), wireless sensor networks (2001-now), to smart grid (2012-now). He is an Associate of (ISC)2, i.e., an industry-recognised security professional. Recently, he has been working on applying game theory to the risk assessment and cyber security problem of the smart gird; for which he has been developing simulations of complex power systems. Dr Law is a named investigator in several local and European projects, and is experienced in organizing conferences (e.g., IEEE ISSNIP), and building industry linkages. Dr Law's publications include 3 book chapters, 9 journal articles, 29 conference papers, and 2 edited volumes, earning him a Google Scholar H-index of 13.Share this:
