【摘要】：近年来,智能电网技术的发展和研究受到学者的广泛关注。作为下一代新型电网,智能电网是将传统电网和先进的通信及信息控制技术相结合,能够实现电力与信息的双向传输的新型电网。智能电网能够实现双向、高速的数据传输和信息控制,以达到实时的参数采样。然而,频繁地数据采集在满足实时管理的同时带来了用户敏感信息泄露的问题。因此,隐私保护成为智能电网中一个重要的安全需求。电动汽车加入电网(Vehicle-to-Grid,V2G)作为智能电网的重要组成部分,不仅能够为电网提供很好的辅助服务,而且可以促进可再生资源的使用。在V2G网络中,电动汽车和电网之间的信息传输可能面临各种网络安全的攻击。为了保证通信的有效性,通信双方在进行信息传输之前,必须进行身份认证。论文对智能电网中的数据收集和V2G网络中的身份认证进行了系统地研究,所取得的研究成果为:1.针对智能电网中数据收集的隐私保护的安全需求,提出了一种适用于智能电网的具有隐私保护的数据收集方案。通过采用盲签名技术和密钥分配技术来实现用户数据的隐私保护,性能分析表明,与已有方案相比,该方案不仅可以提供用户的隐私保护,而且计算量较小。2.针对V2G网络中身份认证的安全需求,提出了一种跨域的身份认证方案。首先,根据群组中群成员的特点设计跨域身份认证方案的系统模型;然后,通过群盲签名技术实现在不揭露用户身份隐私及行车路线的情况下,完成对电动汽车身份的跨域认证。综合的安全性分析表明,该认证方案不仅可以实现对用户的隐私保护,而且实现了电动汽车身份的跨域认证。
[Abstract]:In recent years, the development and research of smart grid technology has been widely concerned by scholars. As the next generation of new power grid, smart grid is a new type of power grid, which combines the traditional grid with the advanced communication and information control technology, and can realize the two-way transmission of power and information. Smart grid can realize two-way, high-speed data transmission and information control to achieve real-time parameter sampling. However, the frequent data acquisition not only satisfies the real-time management, but also brings the problem of user sensitive information leakage. Therefore, privacy protection has become an important security requirement in smart grid. As an important part of smart grid, electric vehicle (EV) can not only provide good auxiliary service for power grid, but also promote the use of renewable resources. In V2G networks, the transmission of information between electric vehicles and power grids may face various network security attacks. In order to ensure the validity of communication, both parties must authenticate their identity before transmitting information. In this paper, data collection in smart grid and identity authentication in V2G network are systematically studied, and the research results are as follows: 1. Aiming at the security requirement of privacy protection for data collection in smart grid, a data collection scheme with privacy protection for smart grid is proposed. Blind signature and key distribution techniques are used to protect the privacy of user data. The performance analysis shows that the proposed scheme can not only provide privacy protection for users, but also have less computation. Aiming at the security requirement of identity authentication in V2G network, a cross-domain authentication scheme is proposed. Firstly, according to the characteristics of group members, the system model of cross-domain identity authentication scheme is designed. Complete cross-domain authentication of electric vehicle identity. The comprehensive security analysis shows that the authentication scheme can not only protect the privacy of users, but also realize the cross-domain authentication of electric vehicle identity.
