Embodiment Construction

[0026] The content of the present invention will be described in more detail below:

[0027] The present invention proposes a blind signature block chain design method based on ECC algorithm, which mainly includes the following steps:

[0028] 1) Use go language to realize blind signature code;

[0029] 2) Select the hyperledger code source code, modify it in the source code, and use the blind signature method where the endorsement node performs digital signature;

[0030] 3) Recompile the hyperledger source code for package deployment;

[0031] 4) After the deployment is completed, it is put into operation and the transformation is completed.

[0032] The specific implementation process is as follows:

[0033] 1). Use the ECC algorithm to generate public-private key pairs for the blockchain client or node, or obtain a digital certificate from a third-party CA. The digital certificate contains the key pair; the public parameters used are as follows: G(x 1 , Y 1 ) As the base point, E P (a...

Abstract

The invention provides a block chain design method of blind signature based on ECC algorithm, The invention belongs to the cross technical field of cryptography and block chain. In the prior block chain deployment process, the invention realizes blind signature algorithm by using go language, reconstructs the original signature flow, adds blind signature module to block chain code for deployment,and completes blind signature reconstruction of block chain. Blind signature based on digital signature has anti-forgery and anti-repudiation characteristics, and can blind the message, and will not disclose any message content and information to the signer. The signer can not deduce the content of the signature according to the parameters, so it can be applied to the block chain system very well.

Description

Technical field [0001] The present invention relates to the cross technology of cryptography and block chain, in particular to a block chain design method of blind signature based on ECC algorithm. Background technique [0002] Blockchain is a kind of data that is jointly maintained by multiple parties and stored in a block chain structure. It uses cryptography to ensure transmission and access security, and can be stored all the time and cannot be tampered with. All transactions are broadcast in the blockchain, and consensus is formed between nodes through a consensus mechanism. Node members can consult relevant transaction records according to their authority, but no node can easily control and change the data of the entire network. Due to its decentralization, tamper-proof, anonymization and other characteristics, transaction trust is determined by machines and algorithms, and the transaction process is automatically executed by programs, which can reduce the cost of trust an...
