As an integral part of V2G networks, EVs receive electricity from not only the grid but also other EVs and may frequently feed the power back to the grid. Payment records in V2G networks are useful for extracting user behaviors and facilitating decision-making for optimized power supply, scheduling, pricing, and consumption. Sharing payment and user information, however, raises serious privacy concerns in addition to the existing challenge of secure and reliable transaction processing. In this article, we propose a blockchain-based privacy preserving payment mechanism for V2G networks, which enables data sharing while securing sensitive user information. The mechanism introduces a registration and data maintenance process that is based on a blockchain technique, which ensures the anonymity of user payment data while enabling payment auditing by privileged users. Our design is implemented based on Hyperledger to carefully evaluate its feasibility and effectiveness.

基于区块链的车到电网网络隐私保护支付机制


作为V2G网络的组成部分，电动汽车不仅从电网接收电力，还从其他电动汽车接收电力，并可能频繁地将电力反馈回电网。 V2G 网络中的支付记录对于提取用户行为和促进优化供电、调度、定价和消耗的决策非常有用。然而，除了安全可靠的交易处理的现有挑战之外，共享支付和用户信息还引发了严重的隐私问题。在本文中，我们提出了一种基于区块链的 V2G 网络隐私保护支付机制，该机制可以在保护敏感用户信息的同时实现数据共享。该机制引入了基于区块链技术的注册和数据维护流程，保证了用户支付数据的匿名性，同时允许特权用户进行支付审计。我们的设计是基于Hyperledger来实现的，仔细评估其可行性和有效性。
