Signature processing method, related device and equipment

Abstract

The invention discloses a signature processing method, which comprises the steps of obtaining first to-be-processed data of a first blockchain node, the first to-be-processed data comprising first target data; sending first target data in the first to-be-processed data to a signature server, so as to enable the signature server to perform signature processing on the first target data by adopting the private key to obtain signature information; receiving signature information sent by the signature server; and sending the signature information to the second blockchain node, so as to enable the second blockchain node to update the blockchain account book according to the signature information. The invention further discloses a signature processing device and equipment. The whole signature processing process is carried out in the signature server, and the private key is stored at the signature server side, so that the hidden danger of private key leakage caused by the fact that the blockchain node is broken through can be prevented, the signature processing work is stripped from the blockchain node, and the workload of the blockchain node is reduced.

Description

technical field [0001] The present application relates to the technical field of information security, and in particular to a signature processing method, related device and equipment. Background technique [0002] The blockchain provides a trust mechanism and has the potential to change the financial infrastructure. All kinds of financial assets can be integrated into the blockchain ledger and become digital assets on the chain, which are stored, transferred and traded on the blockchain. The decentralization of blockchain technology can reduce the transaction costs of financial enterprises and make transactions more convenient, intuitive and secure. [0003] At present, the private key of the blockchain node is stored in the local configuration file, and the blockchain node uses the local private key to implement signature processing, such as signing or verification processing. [0004] However, once the blockchain node is attacked, it is likely to cause the leakage of the...

AI Technical Summary

Problems solved by technology

[0004] However, once the blockchain node is attacked, it is likely to cause the leakage of the private key, which will lead to more serious losses, such as the theft of digital assets or private data

At the same time, blockchain nodes often need to process a large amount of data, and the operation of signature processing will bring a large workload to blockchain nodes
