Problems solved by technology

The signature verification process involves complex cryptographic algorithms, which is a huge performance loss for the blockchain
With the increase of blockchain nodes and transactions, the signature verification data is frequently repeated between each node and within the node. At this time, the impact of signature verification on performance will be very obvious, especially in the case of high concurrent access, each node is synchronized with each other Block or transaction, each node needs to verify the block and transaction to ensure that the data source is reliable and cannot be tampered with; inside the node, the private key of the issuer needs to be used to sign the transaction when it is sent, and when the transaction enters the transaction pool It is necessary to verify the signature of the transaction, and it is also necessary to verify the signature of this transaction during consensus. A large number of repeated signature verification operations cause unnecessary performance loss, and may even cause the node to be unable to respond to the outside world for a long time, affecting the user experience

Embodiment 1

[0055] like figure 1 As shown, Embodiment 1 of the present disclosure provides a blockchain high-concurrency signature verification method based on a trusted secret key system, which includes four steps, namely: signature operation, signature verification operation, cache maintenance, and cache health check .

[0056] Step 1: Signature Operation

[0057] like figure 1 As shown, the chain node receives data that needs to be signed from external applications or other nodes, calls the signature method in the signature verification device, and then returns the signature result to the chain node.

[0058] Step 2: Signature verification operation

[0059] like figure 2 As shown, the chain node receives the data that needs to be verified from external applications or other nodes, and first determines whether the signature has been verified and exists in its own cache according to the identifier held by the data to be verified. If it exists, it will directly return the verificati...

Embodiment 2

[0070] like Figure 4 , Figure 5 and Image 6 As shown, Embodiment 2 of the present disclosure provides a blockchain high-concurrency signature verification system based on a trusted secret key system, including a signature verification device and at least two block nodes, each of which is connected to the signature verification device. communication connection;

[0071] Both the node and the signature verification device include a cache for storing the verified data. When the node and the signature verification device receive a signature verification request, if there is this piece of data that has been verified in the cache, the verification result will be directly stored. return to the caller;

[0072] Otherwise, the signature verification device performs signature verification on the data sent by the node, returns the result to the node, and saves the result in the cache, and the node saves the signature verification data in the cache for direct acquisition when the ne...

Abstract

The present disclosure provides a blockchain high-concurrency signature verification method and system based on a trusted secret key system. Multiple nodes share the same independent signature verification device; The cache of the verified signature data, when the node and the signature verification device receive the signature verification request, if there is this piece of data that has been verified in the cache, the signature verification result is directly returned to the caller; otherwise, the signature verification device The data sent by the node is verified for signature, and the result is returned to the node. The signature verification device and the node save the signature verification data in their respective caches for direct acquisition by the next node; The signature verification function is independent of the external signature verification device, which reduces the performance loss of blockchain nodes and improves the concurrency capability of blockchain nodes.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain, and in particular, to a blockchain high-concurrency signature verification method and system based on a trusted secret key system. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] Digital signature technology is used in the blockchain to prevent malicious forgery or tampering of data when sending information, and to ensure the authenticity and credibility of the data. For example, each transaction in the blockchain needs to be signed with the private key of the transaction initiator, and multiple repeated signature verifications are required during the verification and execution of the transaction; when synchronizing blocks between nodes, the The node will sign the block first, and then broadcast the block to other nodes. After other nodes receive the block, t...
