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

 

 

Talk 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. The smart home system 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, an attacker could tamper smart meters for electricity bill increase 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. I will conclude the talk with some of the ongoing research conducted in my group and our international collaborators.
