Enhanced security of data dissemination in blockchain-based peer-to-peer smart energy trading network

Abstract

A peer-to-peer (P2P) energy trading network provides a platform that enables households to share surplus energy. Unfortunately, the use of digital platform for energy transactions may raise concerns over privacy breaches, energy data misuse and threats to home security if occupancy patterns are exposed. To address these issues, the network must concurrently provide reliable data sharing, protect user’s privacy and accountability for misbehaviors. Our solution begins with the construction of a generic blockchain-enabled P2P energy trading framework that generalizes the critical operations for secure energy transactions. Consequently, this generic framework serves as the foundation for the construction of our proposed consortium blockchain-enabled data dissemination mechanism in the P2P smart energy trading scheme. The adoption of blockchain in the proposed scheme is supported by the implementation of message-linkable group signature scheme and NBFT consensus mechanism to achieve robust security in decentralized energy trading environment. Additionally, continuous double auction mechanism is integrated in this scheme to connect energy buyers and sellers to engage in transactions consistently. The analysis evaluation demonstrates our proposed scheme is robust against adversarial attacks. delivers performance metrics comparable to existing solutions and achieves throughput requirements for practical real-world establishment.
