摘要：
Smart gird is a new generation of power system, which significantly improves the efficiency, reliability and sustainability of power service. However, the issue of privacy information leakage of users in smart grid is becoming increasingly prominent. To address this problem, we propose a privacy-preserving data security collection scheme, where the collector is able to verify all the collected data and aggregate them into a new data packet, then send it to the electricity service provider (ESP) for decryption and storage. This paper also introduces a third-party to arbitrate disputes between the smart meter users and ESP. In our solution, collectors, ESP, and the third-party can perform batch verification on multiple (aggregated) ciphertexts, respectively, so as to efficiently verify their authenticity and integrity. The theoretical analysis and experimental comparison show that the proposed scheme enjoys more computational efficiency and communication efficiency compared with existing scheme. © 2020, Chinese Institute of Electronics.
