Design of Load Power Data Protection and Verification Mechanism Based on Blockchain

With the deepening of the process of power market, the security of power consumption data acquisition and transmission for load side market participants to participate in power trading has attracted more and more attention. According to the network architecture of power acquisition data uploading step by step, the paper introduces blockchain technology as the protection technology policy of data tamper prevention and replacement. In view of the malicious data protection event that some nodes' private keys are leaked or nodes are hijacked by malicious nodes after the reference to blockchain technology, an identity review mechanism and method of "consensus authentication at the same level, cross level interactive verification" is proposed, giving full play to the node binding method between data verification between nodes at the same level and the vertical network, and providing more secure power data collection and transmission technology support for the development of power market.
