Embodiment 1
[0075] Such as figure 1 As shown, this embodiment proposes a digital certificate management method. The method first establishes a blockchain application system, and then establishes a digital certificate management mode, including certificate generation, cancellation, and update, so as to realize the distributed and automatic distribution of digital certificates. Maintenance and auditable management provide the security and reliability of the entire digital certificate system. The specific implementation process is:
[0076] S1. Establish a blockchain application system and deploy multiple nodes. Each node corresponds to an open and shared ledger, and each ledger records multiple blocks;
[0077] S2. Establish a digital certificate management mode, and record digital certificate generation, digital certificate cancellation and digital certificate update operations synchronously in each ledger.

Embodiment 2
[0103] Such as Figure 6 As shown, this embodiment proposes a digital certificate management system, which includes:
[0104] Blockchain application system building module 1 is used to deploy multiple nodes, each node corresponds to an open and shared account book, and each account book records multiple blocks;
[0105] The digital certificate management mode establishment module 2 is used to synchronously record digital certificate generation, digital certificate cancellation and digital certificate update operations in each ledger.
[0106] preferred, such as Figure 7 As shown, the block chain application system building module 1 includes:
[0107] The node deployment module 3 is used to establish a P2P network and deploy multiple nodes;
[0108] The data recording module 4 is used to enable each node to maintain an open and shared ledger in a one-to-one manner, each ledger records multiple blocks, and each block records multiple pieces of operation or transaction data; ...

Abstract
The invention relates to a digital certificate management method and system, belongs to the field of information security, and aims at solving the problem that application for a digital certificate is low in autonomous flexibility and high in cost at present. The method comprises that a block chain application system is established; and a digital certificate management mode including certificate generation, cancellation and update is established. Digital certificates can be managed in a distributed, self-maintenance and auditable manner, and the safety and reliability of the whole digital certificate system are improved. The digital certificate management system comprises a block chain application system establishing module for disposing nodes, each node corresponds to a public and shared account book, and each account book records multiple blocks; and the digital certificate management system also comprises a digital certificate management mode establishing module for carrying out autonomous digital certificate generation, digital certificate cancellation and digital certificate update operations on each account book.
Description
technical field [0001] The invention relates to the field of information security. Background technique [0002] At present, the encryption of information data and network identity authentication are mainly realized through digital certificate technology. Operations such as generation, renewal, and cancellation of digital certificates are completed by a digital certificate certification authority (CA). The authority and security of digital certificates are guaranteed by CAs. Therefore, the security of application systems based on digital certificate technology depends on CAs, and CAs have become the key points of network attacks. [0003] CA is operated and maintained by a specialized organization, and the security awareness and operation compliance of its managers largely affect the security and authority of CA. [0004] As a centralized authority, CA will reduce the security of the entire application system if it is attacked. At the same time, user groups who want to est...
