面向点对点能源交易市场的隐私保护与可问责计费协议
A Privacy-Preserving and Accountable Billing Protocol for Peer-to-Peer Energy Trading Markets
AI总结：
本文提出PA-Bill协议，通过同态加密与区块链技术结合通用成本分摊和争议解决机制，解决点对点能源交易中承诺与实际交付不符时的隐私保护与可问责计费问题。
摘要：
本文提出了一种用于点对点能源市场交易的隐私保护与可问责计费（PA-Bill）协议，以解决承诺交付的能源量与实际交付量之间可能存在差异的情况。此类差异会在维持准确计费的同时，为同时实现隐私保护和可问责性带来挑战。为克服这些挑战，提出了一种优先考虑隐私和可问责性的通用成本分摊机制。该机制利用同态加密密码系统提供隐私保护，并采用区块链技术建立可问责性。此外，还引入了争议解决机制，以最大程度减少错误账单计算的发生，同时确保整个计费过程中的可问责性和不可抵赖性。评估结果表明，PA-Bill 提供了一种有效的计费机制，利用半去中心化方法在点对点能源市场中维持了隐私保护和可问责性。
英文摘要：
This paper proposes a privacy-preserving and accountable billing (PA-Bill) protocol for trading in peer-to-peer energy markets, addressing situations where there may be discrepancies between the volume of energy committed and delivered. Such discrepancies can lead to challenges in providing both privacy and accountability while maintaining accurate billing. To overcome these challenges, a universal cost splitting mechanism is proposed that prioritises privacy and accountability. It leverages a homomorphic encryption cryptosystem to provide privacy and employs blockchain technology to establish accountability. A dispute resolution mechanism is also introduced to minimise the occurrence of erroneous bill calculations while ensuring accountability and non-repudiation throughout the billing process. Our evaluation demonstrates that PA-Bill offers an effective billing mechanism that maintains privacy and accountability in peer-to-peer energy markets utilising a semi-decentralised approach.
