Aug. 19, 2014 - Prof. Shiyan Hu from Michigan Technological University (MTU) visited CECA and gave a talk on "Physical Design and Smart Home Cybersecurity: The Marriage of CAD and Cyberphysical System".
Abstract: In this talk, I will begin with the discussion on a CAD problem, namely, the interconnect optimization which is a key process for handling ever increasing interconnect delay in the nanometer VLSI design. I will highlight my experience in tackling a major open problem in the field, namely, the timing driven minimum cost buffer insertion problem. My work designs the first fully polynomial time approximation scheme for this problem, which can approximate the optimal solution within a factor of 1+ running in O(m2n2b/3+n3b2/) time for any 0<<1. I will then move on to smart home system and cybersecurity. The massive deployment of advanced metering infrastructure and home energy management system has mandated a transformative shift of the classical grid into a more reliable and secure grid. A smart home system is critical as it controls all the end use components of a grid. However, such a system is vulnerable to cyberattacks such as energy theft and pricing hack. For example, we demonstrate that due to the interdependence between utility pricing and customer energy load, a cyber attacker could tamper smart meters for monetary cost loss of users and energy load unbalancing of the power system. I will also discuss the countermeasures for smart home cyberattacks, which are based on the joint optimization using machine learning and power electronic sensor deployment. As an example, I will describe our recent work on a strategic Feeder Remote Terminal Unit (FRTU) deployment optimization technique based on the cross entropy and the conditional random field techniques for detecting smart meter tampering in the power distribution network.
