Securing the Smart Meter

By: Kris Ardis

Abstract: This article will discuss various techniques to increase the security of the endpoints in the smart grid—meters and sensors that are dispersed far away from the watchful eyes of the utilities. Conventional attacks such as physical and logical attacks on the smart meter will be considered, as well as more coordinated attacks that might infiltrate the supply chain, causing utilities to deploy compromised meters. The technology to address these attacks exists today, has been used successfully for years in the financial payment-processing industry, and can readily be applied to the smart grid.
