An Overview of Privacy-Preserving Data Aggregation in Smart Metering Systems
Growing energy needs forces governments to look for alternative resources and ways of better energy grid management and load balancing. As a major initiative, many countries including the UK, the USA and China have already started deploying smart grids. In this paper, the authors present recent and ongoing research in the field of privacy protection for smart grids, where individual smart meter measurements are kept secret from outsiders, including the utility provider itself, while processing private measurements under encryption is still feasible. They focus particularly on data aggregation, which demonstrates the major research challenges in privacy protection for smart grids.
