Abstract

Multi-microgrid smart electricity market can facilitate energy complementarity between microgrids and improve the utilization rate of renewable energy. However, in the transaction payment between multiple blockchain-based microgrids, transaction data and transaction assets on different blockchains are not only difficult to interoperate, but also attackers can obtain private information such as the account addresses and transaction amount of electricity prosumers from the blockchain ledger. This allows attackers to infer the true identities of users, undermining the security and fairness of electricity transaction. To address these issues, a cross-chain electricity transaction scheme for multi-microgrid with user privacy protection and regulation is proposed. Firstly, Pedersen commitment is used to encrypt the transaction amount, and Signature of Knowledge is used to encrypt the electricity transaction payment message while hiding the true identities of the users, achieving anonymous payment. Secondly, the stealth address generation algorithm in the blockchain is improved, achieving unlinkability between users' real address and payment address, preventing inference attacks and enhancing address generation efficiency. Finally, relay chain technology is used to ensure the security of cross-chain electricity transaction payment between different microgrids. Theoretical analysis proves the scheme's unforgeability, anonymity, and traceability. Performance evaluation indicates that the scheme has low computational costs.

一种具有用户隐私保护和监管的多微电网跨链电力交易方案

多微网智能电力市场可以促进微网之间的能源互补，提高可再生能源的利用率。然而，在多个基于区块链的微电网之间的交易支付中，不同区块链上的交易数据和交易资产不仅难以互操作，而且攻击者还可以从区块链账本中获取电力产消者的账户地址、交易金额等私人信息。这使得攻击者可以推断出用户的真实身份，从而破坏了电力交易的安全性和公平性。针对这些问题，提出了一种具有用户隐私保护和监管的多微电网跨链电力交易方案。首先，利用Pedersen承诺对交易金额进行加密，利用知识签名对电力交易支付消息进行加密，同时隐藏用户的真实身份，实现匿名支付。其次，对区块链中的隐身地址生成算法进行改进，实现了用户真实地址与支付地址之间的不可链接性，防止了推理攻击，提高了地址生成效率。最后，利用中继链技术确保不同微电网间跨链电力交易支付的安全性。理论分析证明了该方案具有不可伪造性、匿名性和可追溯性。性能评估表明，该方案具有较低的计算成本。

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
