A Quantum-resistant and Traceable Privacy Protection Scheme for Energy Trading in Multi-microgrids
摘要
Abstract
In multi-microgrid energy trading,insecure communication can lead to eavesdropping and tampering of energy trading information,resulting in the leakage of user privacy and affecting the fairness of transactions.To address this,a privacy-preserving scheme for multi-microgrid energy trading based on quantum-resistant technology and traceability is proposed.Firstly,users participate in energy trading through pseudo-identities to prevent their real identities from being disclosed.Regulatory authorities can identify illegal users by reviewing transaction records on the consortium blockchain and trace their real identities based on the pseudo-identities.Secondly,an algorithm combining certificateless ring signcryption and multivariable public key cryptography is designed to encrypt bidding information,which can resist quantum computing attacks.This algorithm achieves both signature and encryption of transaction messages,ensuring message confidentiality and non-repudiation.Finally,theoretical proofs demonstrate the security of the proposed scheme.Performance analysis and experimental results show that the proposed scheme has low time cost and high computational efficiency.关键词
