A Privacy Protection Scheme for Smart Grid Based on Attribute-based Group Signature

doi:10.3969/j.issn.1671-1122.2019.07.003

Abstract

Abstract:

Smart grid has attracted wide attention in promoting the development of intelligent and distributed power transmission system, but in smart grid, there is a serious risk of privacy information leakage in smart devices. To solve this problem, this paper proposes a privacy protection mechanism, which uses attribute-based group signature (ABGS) to achieve securely authentication between users and access terminals. ABGS allows users and access terminals to authenticate each other, and ensures the anonymity of users, and the control center can trace the user when the user violates the law. This paper formally proves the identity authentication, privacy protection, anti-repetitive attack and traceability of the scheme.

Key words: smart grid, attribute-based group signature, privacy protection, bilinear mapping
