Problems solved by technology

After serializing the entire transaction file, the hashing process requires a lot of computing resources, which is inefficient
[0003] In the existing alliance chain scheme, the signature of the interaction information in the node is to perform a hash operation on the serialization of the entire message body. With the increase of the content of the message body and the increase of nodes, the efficiency of the transaction will become lower

Embodiment Construction

[0045] The present invention will be further explained and described below in conjunction with the accompanying drawings and specific embodiments of the description. For the step numbers in the embodiment of the present invention, it is only set for the convenience of explanation and description, and there is no limitation on the order of the steps. The execution order of each step in the embodiment can be carried out according to the understanding of those skilled in the art Adaptive adjustment.

[0046] In view of the high resource consumption and low efficiency of message signing in the existing technology when signing messages between nodes, the embodiment of this application provides a signature method for nodes in the blockchain, which aims to improve the efficiency of the alliance chain among nodes. Signature efficiency and security.

[0047] In order to achieve the above object, the steps provided by the present invention are:

[0048] 1: The sending node processes t...

Abstract

The invention discloses a signature method and system applied to a block chain and a storage medium, and the method comprises the steps: carrying out the interception of a to-be-transmitted message based on a preset length, and generating an interception data packet; performing hash calculation on the intercepted data packet, and determining signature information; sending the message to be sent, the intercepted data packet and the signature information to a receiving node; and verifying the intercepted data packet and the signature information to obtain information after the verification is passed. According to the invention, after the to-be-sent message is intercepted based on the preset length, hash calculation is carried out on the intercepted data packet, and verification is carried out according to the intercepted data packet, so that the resource consumption during message signature between nodes can be reduced, the message signature efficiency is improved, and the method can bewidely applied to the technical field of block chains.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a signature method, system and storage medium applied to block chains. Background technique [0002] The alliance chain is composed of multiple nodes, and the information interaction between nodes needs to be signed to ensure security. The sending node serializes the entire transaction information file, calculates the hash and generates a signature through its own private key, and the receiving node receives The information first serializes the entire transaction file and then calculates the hash to verify the signature through the sender's private key. After serializing the entire transaction file, the hashing process requires a lot of computing resources, which is inefficient. [0003] In the existing consortium chain scheme, the signature of the interaction information in the node is to perform a hash operation on the serialization of the entire message body. As the cont...
