Secure Online Metering for a Liberalized Energy Market

Abstract

The liberalization of the energy market requires frequent online access to metering devices. That is not only necessary for exchanging meter data, but also for management reasons. The integration of strong security mechanisms is an essential requirement for the introduction of online meter device access. The project SELMA (Secure Electronic Exchange of Metering Data) supported the development of a concept, the implementation and a field trial test of prototypes of such metering devices. This paper focuses on the security aspects. It describes the security analysis, the required security services and the security concept. The security concept includes the security mechanisms and cryptographic techniques applied to the metering data as well as the security management.
