【Abstract】As a key component of smart grid (SG), advanced metering infrastructure (AMI) realizes two-way communication between users and power companies. Considering that AMI involves a large number of important data, which are related to the measurement of users' electricity bills and the decisionmaking of power suppliers. Therefore, it is necessary to strengthen the protection of AMI data security and privacy to avoid economic losses caused by data leakage and tampering. Aiming at the problems of trust and single point of failure in the existing protection schemes, this paper proposes an AMI security framework based on blockchain. By combining the characteristics of blockchain such as decentration, tamper proof, traceability, the architecture of AMI data management system is reshaped. The technologies of peer-to-peer (P2P) transmission, asymmetric encryption, consensus algorithm and smart contract of blockchain are used to solve the problems of secure storage, transmission and application of AMI data. Through theoretical analysis and experiments, the feasibility of introducing blockchain technology into AMI is verified. The results show that the proposed framework is secure and reliable, which provides a strong guarantee for AMI data security and privacy protection. (c) 2022 Elsevier Ltd. All rights reserved.
