The emerging proportion of renewable energy resources penetration and the rapid popularity of Electric Vehicles (EVs) have promoted the development of the Internet of Electric Vehicles (IoEV), which enables seamless EV’ information collection and energy delivery by leveraging wireless power transfer. However, vulnerabilities in internet infrastructure and the self-interested behavior of EVs pose significant security and privacy risks during energy delivery in IoEV. In addition, EVs often lack the incentive to cooperate for regional energy balance. To tackle these questions, this paper proposes a blockchain-based privacy-preserving incentive mechanism for energy delivery in IoEV. Based on cryptographic technology, this paper introduces a group signature scheme with self-controlled and sequential linkability, which safeguards the privacy of EV users and ensures transaction records maintain exact sequence during energy delivery. Furthermore, an incentive mechanism based on co-utile reputation management is presented to encourage EV users to participate honestly and cooperatively in energy delivery. Moreover, a comprehensive security analysis of the proposed group signature scheme and incentive mechanism is given. Finally, extensive experimental results demonstrate the feasibility and efficiency of the proposed approach compared to existing schemes.

基于区块链的电动汽车互联网隐私保护激励计划


可再生能源资源渗透率的提高和电动汽车 （EV） 的迅速普及推动了电动汽车互联网 （IoEV） 的发展，通过利用无线电力传输实现电动汽车的无缝信息收集和能源输送。然而，互联网基础设施的漏洞和电动汽车的自私行为在车联网能源输送过程中构成了重大的安全和隐私风险。此外，电动汽车往往缺乏为区域能源平衡进行合作的动力。为了解决这些问题，本文提出了一种基于区块链的 IoEV 能量传输隐私保护激励机制。该文基于密码技术，介绍了一种具有自控和顺序可链接性的群签名方案，保护了电动汽车用户的隐私，并确保交易记录在能量传输过程中保持准确的顺序。此外，提出了一种基于共益声誉管理的激励机制，以鼓励电动汽车用户诚实和合作地参与能源输送。此外，该文还对所提出的群体签名方案和激励机制进行了全面的安全性分析。最后，大量的实验结果证明了与现有方案相比，所提出的方法的可行性和有效性。
