At present, most privacy-preserving data aggregation schemes in smart grid achieve privacy data protection through homomorphically encrypted data aggregation. However, these data aggregation schemes tend to rely on a trusted third party (TTP), and fail to efficiently handle the case of a meter failure. Besides, they are less flexible for overall user management, and resistance to collusion attacks needs to be improved. In this paper, we propose an efficient and robust privacy-preserving data aggregation scheme without TTP, called EFTA. Overall, the scheme eliminates the reliance on a TTP, combines with Shamir threshold secret sharing scheme to increase overall fault tolerance, supports flexible and dynamic user management, and effectively defends against entity initiated collusion attacks. According to security and performance analysis results, the scheme proposed in this paper meets the multiple security requirements of smart grid, and is more efficient in terms of overall overhead compared to the existing privacy-preserving data aggregation schemes.<\/jats:p>","DOI":"10.1093\/comjnl\/bxae012","type":"journal-article","created":{"date-parts":[[2024,2,25]],"date-time":"2024-02-25T10:04:54Z","timestamp":1708855494000},"page":"2368-2378","source":"Crossref","is-referenced-by-count":5,"title":["EFTA: An Efficient and Fault-Tolerant Data Aggregation Scheme without TTP in Smart Grid"],"prefix":"10.1093","volume":"67","author":[{"given":"Xianyun","family":"Mei","sequence":"first","affiliation":[{"name":"College of Computer Science and Technology, Shanghai University of Electric Power , Shanghai , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liangliang","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Shanghai University of Electric Power , Shanghai , China"},{"name":"Advanced Cryptography and System Security Key Laboratory of Sichuan Province , Chengdu , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baodong","family":"Qin","sequence":"additional","affiliation":[{"name":"School of Cyberspace Security, Xi\u2019an University of Posts and Telecommunications , Xi\u2019an , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Shanghai University of Electric Power , Shanghai , China"},{"name":"Advanced Cryptography and System Security Key Laboratory of Sichuan Province , Chengdu , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Long","sequence":"additional","affiliation":[{"name":"School of Electronic Information and Electrica Engineering, Shanghai Jiao Tong University , Shanghai , China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,2,22]]},"reference":[{"key":"2024062414163524000_ref1","doi-asserted-by":"crossref","first-page":"2153","DOI":"10.1109\/JIOT.2021.3090270","article-title":"The secure lattice-based data aggregation scheme in residential networks for smart grid","volume":"9","author":"Qian","year":"2022","journal-title":"IEEE Internet Things J."},{"key":"2024062414163524000_ref2","doi-asserted-by":"crossref","first-page":"103","DOI":"10.1016\/j.inffus.2019.10.008","article-title":"Entropy-driven data aggregation method for energy-efficient wireless sensor networks","volume":"56","author":"Zhang","year":"2020","journal-title":"Inform.
