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

The fine-grained and large number of measurements collected by smart meters can be used to reconstruct consumer behavior, and thus their widespread deployment for the modernization of electricity distribution networks has been associated with privacy concerns. This paper proposes an efficient and privacy-friendly hop-by-hop data aggregation scheme and a billing solution for smart grid systems. In our approach, hop-by-hop communication is utilized for transmitting usage reports of the smart meters. From the outcome of the security and performance analyses we can argue that our proposed scheme is secure and computationally more efficient, as compared to the other solutions.
