Homomorphic Primitives for a Privacy-friendly Smart Metering Architecture

Benjamin Vetter, Osman Ugus, Dirk Westhoff, Christoph Sorge

Abstract

We propose a privacy-friendly smart metering architecture which is yet flexible enough to serve various future third party energy services. Our secure architecture may be deployed as a cloud service and allows processing of SQL queries on encrypted measurements, providing aggregated results in a most flexible manner. A combination of homomorphic encryption and homomorphic MACs provides confidentiality of the users’ energy consumptions, allowing integrity checks and enhanced SQL-queries on encrypted data. Our extensive performance analysis shows that our approach is promising with respect to storage and computational overhead.
