Alliance chain block chain bottom layer-based electronic archive data interaction method

Abstract

The invention discloses an alliance chain block chain bottom layer-based electronic archive data interaction method, which comprises a data layer, a network layer, a consensus layer and an application layer, and is characterized in that the data layer comprises block data, a chain structure, a digital signature, a Merkle tree and a timestamp; the network layer is used for constructing a P2P network, a propagation mechanism and a verification mechanism between block chain nodes; the consensus layer is used for confirming a consensus mechanism of the regional chain, and the application layer comprises an intelligent contract and a virtual machine. According to the invention, the problem of eavesdropping in the transmission process is solved by using the safety communication technology of the block chain technology; a chain type storage structure of the block chain is applied, so that the archive file can be effectively prevented from being maliciously tampered; the modification of the archive file by applying the block chain technology can be recorded and cannot be tampered, and the change track of the archive can be effectively recorded to play a traceability role; the signature encryption technology in the block chain technology is applied, so that safe interaction of archive files can be guaranteed, and the confidentiality requirement is effectively guaranteed.

Description

technical field

[0001] The invention relates to the field of data interaction, and specifically refers to a method for electronic file data interaction based on the bottom layer of the alliance chain block chain. Background technique

[0002] Solutions to electronic archives Electronic archives ensure that electronic archives information is eavesdropped, leaked, tampered with and forged, which is the core issue of electronic archives information security.

[0003] Blockchain technology, also known as distributed ledger technology, is an emerging technology in which several computing devices jointly participate in "bookkeeping" and jointly maintain a complete distributed database. Since blockchain technology has the characteristics of decentralization, openness, transparency, and secure password mechanism, it is difficult to tamper with, traceable, each connected computing device can participate in data recording, and data synchronization between computing devices can be quic...

[0034] step 1:

[0035] The archives department submits the archive file package by calling the interface provided by the system described in the present invention in the original archive system, and the system smart contract invokes the virus pre-check and kill mechanism to check and kill the uploaded files, and analyzes and extracts the archive package information according to the file record specification. Store the file name, file number, package hash value, name of the file in the package, file creation time, file type, file size, file hash, etc. into the file metadata list, and then store the file metadata, encrypted package file and the signature file of the encrypted private key are submitted to the production node.

[0036] Step 2:

[0037] The production node receives the archive metadata and archive files for verification, and extracts the version number, hash value of the previous block, Merkle tree root value, and timestamp information to generate a "block header...
