Problems solved by technology

Hackers can then use these revoked problematic certificates to illegally join the blockchain, and the blockchain nodes will also use the tampered information when confirming the validity of the certificate, thus posing a threat to the security of the blockchain
What's more, the private key of the CA center may also be stolen by hackers, and hackers can issue digital certificates arbitrarily, threatening the security of the blockchain network

Abstract

The application discloses a digital certificate management method which comprises the steps of: receiving a digital certificate uplink request sent by a node in a block chain, wherein the digital certificate uplink request comprises a to-be-checked digital certificate generated by the node by using a private key signature and is used for requesting to write the to-be-checked digital certificate into the block chain; determining a result of carrying out consensus checking on the to-be-checked digital certificate of the node; and according to the result of consensus checking, determining whether to write the to-be-checked digital certificate into the block chain. The application further discloses a corresponding device, electronic equipment and the like.

Description

technical field [0001] The application relates to the field of computer technology, in particular to a method, device and electronic equipment for managing digital certificates. Background technique [0002] With the development of computer technology, blockchain technology (also known as distributed ledger technology) is favored for its advantages of decentralization, openness, transparency, immutability, and trustworthiness. It is widely used in smart contracts, securities transactions, e-commerce, The Internet of Things, social communication, file storage, proof of existence, identity verification, equity crowdfunding and many other fields have been widely used.
