一种基于ABGS的智能电网隐私保护方案

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

智能电网在促进智能化和分布式电力传输系统的发展方面受到了广泛关注,但是在智能电网中,智能设备存在严重的隐私信息泄露风险。针对该问题,文章提出一种隐私保护机制,该机制使用基于属性群签名(ABGS )安全地实现用户到接入端之间的认证。基于属性群签名允许接入端与用户端相互认证,并且能够确保用户的匿名性,且用户出现违法行为时,控制中心还能追踪到用户。文章针对方案的双向身份验证、隐私保护、抗重复攻击及可追踪性进行了形式化证明。

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.
