论文摘要
近年来，全球电动汽车（EV）的受欢迎程度一直在上升。智能电网将是电动汽车充电和有效消耗电动汽车的主链。随着对电动汽车的需求，相关的网络威胁也在增加。用户在收取电动汽车的同时暴露了他们的个人信息，从而导致隐私威胁。本文提出了一种用户授权的，具有隐私意识认证的密钥交换协议，用于智能电网中的EV充电。所提出的协议基于分散的标识符（DID）和可验证的凭证（VC）的概念。 DIDS的使用使用户可以帮助他们完全控制自己的身份。充电站和用户在使用VC进行充电服务之前验证另一方是否合法。关键恢复是我们在本文中解决的另一个问题。恢复丢失密钥的方法被纳入了建议的协议中。我们提供正式的安全证明和非正式分析，以表明协议对几次攻击的鲁棒性。我们还提供了详细的性能分析，以表明所提出的协议是有效的。
The popularity of Electric Vehicles (EVs) has been rising across the globe in recent years. Smart grids will be the backbone for EV charging and enable efficient consumption of electricity by the EVs. With the demand for EVs, associated cyber threats are also increasing. Users expose their personal information while charging their EVs, leading to privacy threats. This paper proposes a user-empowered, privacy-aware authenticated key exchange protocol for EV charging in smart grid. The proposed protocol is based on the concept of Decentralized Identifier (DID) and Verifiable Credentials (VCs). The use of DIDs empowers users by helping them to have complete control over their identities. The charging station and the user verify that the other party is legitimate before proceeding with the charging services using VC. Key recovery is another issue we address in this paper. A method to recover lost keys is incorporated into the proposed protocol. We present formal security proof and informal analysis to show that protocol's robustness against several attacks. We also provide a detailed performance analysis to show that the proposed protocol is efficient.
