Blockchain-based trusted access authentication method and system for electric power Internet of Things terminal

The invention provides an electric power Internet of Things terminal trusted access authentication method and system based on blockchain, and the method comprises the steps: presetting an access terminal, and constructing an initialized authentication center; enabling the access terminal to request for endorsement from the endoser node, and allowing the request to access the intranet; after access, sending an authentication request, enabling an order node to sort the request, packing the request into a block, broadcasting the block to a peer node, and performing distributed authentication on the requests by calling a kafka module; enabling the committingpeer node to verify the request, marking the request as legal after the request passes verification, writing the request into an account book, judging whether the access terminal is a superior node or not, and joining an authentication center if the access terminal is the superior node. According to the power Internet of Things terminal trusted access authenti
