A secure architecture for smart meter systems

We present a new architecture for a secure smart metering system. Our architecture is based on a special purpose hardware security module that encapsulates all security critical operations and provides the main functionality of the system in an active role. This new approach enables secure meter data handling within the smart grid. As a result, our architecture preserves the privacy of sensitive consumer data and the integrity of meter data. Additionally, our proposed solution enhances the security of components critical to the operation of the power grid.
