A Secure and Privacy-preserving Protocol for Smart Metering Operational Data Collection
This addresses privacy and security concerns for users and operators in smart grid systems, though it is incremental as it builds on existing multiparty computation techniques.
The paper tackles the problem of collecting smart metering data securely and privately by proposing a novel protocol using secure multiparty computation, which enables accurate fee calculations while protecting user privacy, with performance evaluations showing practical implementation in C++.
In this paper we propose a novel protocol that allows suppliers and grid operators to collect users' aggregate metering data in a secure and privacy-preserving manner. We use secure multiparty computation to ensure privacy protection. In addition, we propose three different data aggregation algorithms that offer different balances between privacy-protection and performance. Our protocol is designed for a realistic scenario in which the data need to be sent to different parties, such as grid operators and suppliers. Furthermore, it facilitates an accurate calculation of transmission, distribution and grid balancing fees in a privacy-preserving manner. We also present a security analysis and a performance evaluation of our protocol based on well known multiparty computation algorithms implemented in C++.
