Abstract

The invention discloses a blockchain-based digital certificate management method, system, device, and storage medium. In the method, the certificate template can only be issued after a registration procedure, and strict control is carried out from the root of certificate issuance, and , the voucher template and sending records of each certificate can be traced, which completely solves the problem of certificate forgery, reduces the cost of certificate inspection, and improves the efficiency of certificate inspection. Before issuing and verifying certificates, a secure connection needs to be established between the applicant and the issuer, and between the holder and the verifier. The DID technology adopted provides the basis for secure communication and increases the security of certificate delivery. In addition, the certificate verifier can complete the validity verification of the certificate based on the verifiable statement provided by the holder, and the generation process of the verifiable statement combines zero-knowledge proof, Merkle tree and other cryptographic techniques to selectively disclose the certificate attribute, which can protect the privacy of the certificate holder from being leaked and improve security.

Description

technical field

[0001] The present invention relates to the technical field of digital certificate management, in particular, to a blockchain-based digital certificate management method, system, device, and computer-readable storage medium. Background technique

[0002] The existing certificate issuance and verification process is: X1: the certificate issuer issues a certificate to a qualified person; X2: the certificate holder provides the certificate held by the verifier for verification; X3: the verifier verifies the certificate The certificate provided by the holder is verified. Among them, the existing certificate issuance and verification process has the following disadvantages:

[0003] 1. In the traditional certificate issuance and verification process, a large number of paper certificates are involved in the issuance and verification. In most cases, the verifier has no direct contact with the certificate issuer, so it is necessary to verify with the certificate iss...
