Problems solved by technology

[0003] However, most of the existing certificate authentication systems use two parties for data transmission and processing, which is not only low in transparency and vulnerable to attack and tampering, but also cannot carry out joint supervision and participation of the same industry for the certification requirements of the same certificate. It is easy to cause the credibility of the certificate to be low, and a new system and usage method need to be proposed

Abstract

The invention discloses a certificate authentication method and system based on a block chain. The system includes user equipment and a server, wherein the user equipment comprises demand user equipment and voting user equipment; the server comprises a certificate management server, a public server and a certificate secrecy server. The demand user equipment is connected to the certificate management server and the public server. The voting user equipment is connected to the public server; the public server is connected to the block chain; wherein the block chain generates a block chain node; the certificate management server is connected with a certificate security server; the certificate security server is connected with a public key generation module, is connected with the server throughdemand user equipment and voting user equipment, adopts a mode of separating a public key from a private key, and is combined with a block chain to open vote authentication data, so that the transparency of transparent authentication is effectively improved, tampering is avoided, and use and popularization are facilitated.

Description

technical field [0001] The present invention relates to the field of certificate authentication, and more specifically, to a blockchain-based certificate authentication method and system. Background technique [0002] At present, authentication certificates are widely used in the Internet and e-commerce fields. The traditional method of generating authentication certificates is to establish a centralized certificate authentication center based on public key infrastructure. [0003] However, most of the existing certificate authentication systems use two parties for data transmission and processing, which is not only low in transparency and vulnerable to attack and tampering, but also cannot carry out joint supervision and participation of the same industry for the certification requirements of the same certificate. It is easy to cause the credibility of the certificate to be low, and a new system and usage method need to be proposed. Contents of the invention [0004] In ...
