工业互联网标识元数据可信认证模型设计

Identity is the foundation of the industrial Internet interconnection of everything. The secure storage of identity metadata is worth paying attention to. This paper designs a trusted authentication model of identity metadata, hashes the identity metadata and saves it on the blockchain, and adds a trusted field to the identity template, which is used to store the hash value generated after the identification metadata is linked, so as to facilitate the subsequent trusted authentication. When the integrity authentication of identity data is required, the data stored on the chain is searched according to the transaction hash and compared with the hash value of the current identity metadata information. If the two values are consistent, the trusted authentication passes. Finally, a smart contract is written based on Ethereum to verify the feasibility of the model.
