Title:
CONSORTIUM BLOCKCHAIN CONSENSUS IDENTITY AUTHENTICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/115850
Kind Code:
A1
Abstract:
The present invention provides a consortium blockchain consensus identity authentication method. A user joins a consortium blockchain by means of an access mechanism of the consortium blockchain to become a consortium member. A supervision node operates an initialization algorithm to generate a public parameter PK, generates digital identity information according to unique identifier information of the consortium member, uploads the public parameter PK and the digital identity information to the blockchain, and then generates a corresponding identity private key for the consortium member of each node by means of a key generation algorithm. The beneficial effects of the present invention are that: a data transmission process can be ensured not to be tampered, and identity information of the signer can be identified; the present invention is applied to public data resource development and utilization scenarios; and the combination with an identity signature-based technology not only realizes efficient and safe access control but also expands use scenarios of a consortium blockchain, thereby solving the problem of quickly and safely achieving identity authentication between consensus nodes in the context of a consortium blockchain.
