Smart Home Cybersecurity: Threat and Defense in a Cyber-Physical System

Speaker:  Shiyan Hu – Houghton, MI, United States
Topic(s):  Graphics and Computer-Aided Design

Abstract

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. Smart home is critical in this infrastructure as it controls the end use components of a grid. Despite its importance, such a system is vulnerable to various cyberattacks such as energy theft and pricing hack. In this talk, I will describe several of our recent works on smart home cyberthreat analysis and defense technology development. I will first show that due to the interdependence between utility pricing and customer energy load, a cyberattacker could tamper smart meters for electricity bill manipulation and energy load unbalancing, and similarly energy theft could potentially disturb the power system. I will then discuss some advanced control theoretic and algorithmic techniques developed in my group to defend against those cyberattacks, including partially observable Markov decision process (POMDP) based detection and cross entropy optimization based Feeder Remote Terminal Unit (FRTU) deployment optimization. I will conclude the talk with some of the future research directions on this topic.
