Problems solved by technology

However, in this issuance process, once the certificate issuing authority is maliciously attacked, the identity certificate of the client will be maliciously tampered with when issuing it; thus, the existing certificate issuance method is likely to lead to relatively low security and reliability of the identity certificate. Low

Embodiment approach

[0058] In an implementation manner, if the number of the first voting results is greater than the number of the second voting results, it may be determined that the certificate application notification has passed the consensus; otherwise, it may be determined that the certificate application notification has not passed the consensus. In one embodiment, if the number of the first voting result is greater than the number threshold, it can be determined that the certificate application notification has passed the consensus; otherwise, it can be determined that the certificate application notification has not passed the consensus; Requirements setting. In one embodiment, if the ratio between the number of first voting results and the number of consensus nodes in the blockchain network (that is, the number of total voting results) is greater than a preset value, it can be determined that the certificate application notification has passed the consensus ; Otherwise, it can be determ...

specific Embodiment approach

[0076] In the specific implementation process, if the registration success notification returned by the consensus node is received, it can be determined that the consensus node has registered the node information of the trusted node on the blockchain, and agreed to the trusted node to activate the certificate issuance. Therefore, after receiving the registration success notification returned by the consensus node, the trusted node can start the certificate issuance service in the trusted execution environment. In addition, the trusted node can also load the root certificate through the certificate signing service in the trusted execution environment, so that the root certificate can be used to issue the identity certificate for the client later. Among them, in the trusted execution environment, the specific implementation method of loading the root certificate through the certificate signing service is as follows:

[0077] First, the trusted node can generate a key pair using ...

Abstract

The embodiment of the present invention discloses a blockchain network-based certificate issuance method, related equipment, and media; wherein, the blockchain network includes consensus nodes and trusted nodes; trusted nodes provide certificate issuance services based on a trusted execution environment, The trusted execution environment refers to a secure area that is located in a trusted node and is isolated from the operating system of the trusted node; the method includes: receiving the certificate issuance request sent by the client, and the certificate issuance request is obtained through consensus in the client's certificate application notification It is sent after the consensus of the nodes; the certificate application notification is used to indicate that the client wants to apply for an identity certificate from the trusted node; in response to the certificate issuance request, an identity certificate is generated for the client in the trusted execution environment; the identity certificate is returned to the client Certificate, and send the issuance completion notification corresponding to the certificate application notification to the consensus node. The embodiment of the present invention can better realize the issuance of the identity certificate, and provide the reliability and security of the identity certificate.

Description

technical field [0001] The present invention relates to the field of Internet technology, in particular to the field of communication technology, in particular to a method for issuing a certificate based on a block chain network, a device for issuing a certificate based on a block chain network, a computer device, a client and a A computer storage medium. Background technique [0002] An identity certificate is a digital authentication mark that marks the identity information of all communication parties in Internet communication. At present, the identity certificate of the client is usually issued by a unified certificate issuing structure; the specific issuing process is as follows: When the client has a certificate issuing requirement, the client sends a certificate issuing request to the unified certificate issuing authority; correspondingly, The certificate issuing authority can issue an identity certificate for the client in response to the certificate issuing request...
