| Summary: | There would be serious cross-domain authentication issue when business terminals access different trust domain nodes in various scenarios. In this regard, a supervisable and trusted identity management blockchain model is proposed in this paper, so as to support flexible cross-domain authentication of terminals by combining blockchain and identity authentication technology. Firstly, a novel blockchain-based trusted identity authentication infrastructure is established, and the authentication is completed by means of hash value verification, where the problem of trusted and efficient access to terminals in the outer domain could be solved. Secondly, to avoid malicious terminals accessing synchronous node data, the authentication mechanism and transaction strategy of terminals are designed based on the hierarchical classification of the certificate the energy and electricity blockchain network. Then credible and dynamic access of terminals and the separation of authority management of read and write transactions could be accomplished. Finally, while ensuring security and certificate validity, the efficiency of terminal cross-domain authentication could be improved compared with existing blockchain cross-domain authentication solutions. |
