Abstract

The invention belongs to the field of digital certificate information safety, and provides a digital certificate issuing system based on a block chain platform. By means of the block chain predictor server of the system and an intelligent contract deployed on the block chain, the whole issuing process of the digital certificate is realized, and finally the relevant information of the issued certificate is stored on the block chain, so that the corresponding certificates can be correspondingly operated on the block chain later, and therefore, by means of the characteristic of de-centralizationof the block chain, the recording and management of the digital certificate are realized through the decentralized block chain platform, the transparency, the audibility and the tamper resistance of the whole issuing process of the digital certificate are improved, and further the potential safety hazard caused by the digital certificate issuing process which takes the certificate issuing organization as the center is further solved.

Description

technical field [0001] The invention belongs to the field of digital certificate information security, and in particular relates to a digital certificate issuing system and method based on a blockchain platform. Background technique [0002] The security in the digital certificate issuance process is very important, especially the transparency in the certificate issuance process is an important indicator for evaluating the security of the certificate issuance. At present, the transparency of certificate issuance is not very good. Regarding the transparency of certificate issuance, Google's Certificate Transparency project is currently more advanced in the market. This project improves the security of digital certificate issuance by realizing the transparency of certificate issuance. sex. However, this project has the following problems: [0003] The transparency of certificate issuance is realized by recording the issued certificates on the centralized server. This transpa...
