An Efficient Privacy-Friendly Multi-Hop Data Aggregation Scheme for Smart Grids

In this article, we propose a privacy-friendly data aggregation scheme for smart grids. In our approach, smart meters transmit their usage reports through multi-hop communication, where an aggregation tree is constructed to minimize the aggregation overhead. Security and performance analyses show that our proposed scheme offers better privacy protection for electricity meter reading aggregation as well as computational efficiency, as compared to the existing solutions.
