Embodiment Construction

[0075] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.

[0076] Such as figure 1 As shown, the preferred embodiment of the present invention provides a blockchain-based digital certificate management method, comprising the following steps:

[0077] Step S1: Register the certificate template on the public ledger of the blockchain, and define the certificate according to the template after successful registration;

[0078] Step S2: The certificate applicant node and the certificate authority node establish a secure connection after mutually confirming their identities;

[0079] Step S3: The certificate authority node sends a digital certificate to the certificate applicant node, and all statement contents of the certificate are signed by the public key DID of the certificate authority node;

[0080] Step S4: The certifi...

Abstract

The invention discloses a digital certificate management method and system based on a block chain, equipment and a storage medium, in the method, a certificate template can be issued only after passing through a registration program, strict management and control are carried out from the root of certificate issuing, the certificate template and a sending record of each certificate can be traced, and the problem of certificate counterfeiting is thoroughly solved, the certificate inspection cost can be reduced, and the certificate inspection efficiency is improved. Before a certificate is issued and verified, a secure connection needs to be established between an applicant and an issuer and between a holder and a verifier, and the adopted DID technology provides a basis for secure communication and increases the security of certificate transmission. Besides, the certificate verifier can complete validity verification of the certificate based on the verifiable declaration provided by the holder, and the generation process of the verifiable declaration is combined with cryptographic technologies such as zero-knowledge proof and Merkel tree to selectively disclose certificate attributes, so that the privacy of the certificate holder can be ensured not to be leaked, and the security is improved.

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...
