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

Embodiment Construction
[0094] The embodiment of this application provides a signature processing method, related devices and equipment. Since the entire signature processing process is carried out in the signature server, on the one hand, the private key is stored on the signature server side, which can prevent blockchain nodes from being On the other hand, the work of signature processing is separated from the blockchain nodes, thereby reducing the workload of the blockchain nodes.
[0095] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and not necessarily Used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein, for example, can be practiced in sequences other than those illustrated or described herein.

The present application discloses a signature processing method, comprising: obtaining first data to be processed of a first block chain node, the first data to be processed includes first target data; sending the first data to be processed to a signature server The first target data, so that the signature server uses the private key to sign the first target data to obtain signature information; receive the signature information sent by the signature server; send the signature information to the second block chain node, so that the second block The chain node updates the blockchain ledger according to the signature information. The application also discloses a signature processing device and equipment. The entire signature processing process is carried out in the signature server, and the private key is stored on the signature server side, which can prevent the hidden danger of private key leakage due to the block chain node being compromised, and strip the signature processing work from the block chain node Come out and reduce the workload of blockchain nodes.
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 signature addition or signature verification. [0004] However, once the blockchain node is attacked, it is likely to cause the leak...
