Blockchain data security method based on multiple signatures

Abstract

The invention discloses a blockchain data security method based on multiple signatures. The method comprises the steps of step 1, registering users; step 2, carrying out multi-signature authentication; step 3, block chain data storage; step 4, carrying out multi-signature decryption; step 5, concluding and storing archives; step 6, comparing later data; manually selecting a block chain data system, searching for a block chain data storage system suitable for a user through multiple comparisons, and connecting and storing the block chain data storage system in a computer; the invention discloses a blockchain data security method based on multiple signatures. Computer-based automatic planning is adopted and an RSA algorithm is used to arrange and conclude user block chain data so that , multi-signature security authentication is facilitated, and the problems that traditional user block chain data storage is low in confidentiality and cannot be subjected to signature authentication confidentiality for multiple times, so that the confidentiality is safer, the storage security of the user block chain data is greatly improved, the block chain data storage is more convenient and faster,and the use is facilitated are solved.

Description

technical field [0001] The invention relates to the field of block chain data, in particular to a multi-signature-based block chain data security method. Background technique [0002] Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. The underlying technology of Bitcoin is a series of data blocks associated with cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information and generate the next block. blocks; general blockchain data storage security adopts the method of secret key encryption, the traditional secret key encryption method adopts manual setting of passwords, single password decryption, which is extremely insecure, and the confidentiality of blockchain data stor...

Problems solved by technology

[0002] Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. Blockchain is an important aspect of Bitcoin Concept, it is essentially a decentralized database, and as the underlying technology of Bitcoin, it is a series of data blocks associated with cryptographic methods, each data block contains a batch of Bitcoin network transactions Information is used to verify the validity of the information and generate the next block; the general blockchain data storage security adopts the secret key encryption method, and the traditional secret key encryption method adopts manual setting of passwords, and single password decryption is extremely insecure. The confidentiality of blockchain data storage is low, and at the same time, blockchain data storage is cumbersome, requiring multiple input passwords to decrypt, which is not conducive to user use; in view of these defects, designing a blockchain data security method based on multiple signatures is very useful. necessary
