Problems solved by technology

[0004] However, RFC7706 and other related documents do not have a corresponding mechanism to ensure the security of data transmission between the recursive DNS and the node, so that the root data (the root data is the zone data of the root zone) may be tampered with during the data transmission process, which will lead to large-scale of domain name hijacking incidents

Abstract

The invention discloses a blockchain-based DNS root data distribution method and system. The root data of a root node are obtained through a pre-established miner node in a root data distribution network, then the freshness of the obtained root data is compared with that of the root data of the latest block on a local blockchain, the root data are verified based on the blockchain technology, basedon the characteristics of the blockchain technology, if a large number of links need to be hijacked, it is necessary to tamper more than half of the miner node data, so that the difficulty is large,and a DNS root data distribution network is formed via various miner node networks in the blockchain technology to reduce the tampering risk of the data. Furthermore, zone data of the root node are verified by the blockchain technology to improve the security of the obtained root data, and the network fastness of root data distribution is achieved through a blockchain network.

Description

Technical field [0001] The present invention relates to the field of Internet technology, in particular to a method and system for distributing DNS root data based on blockchain. Background technique [0002] DNS (Domain Name System, Domain Name System) is a distributed database on the Internet as a mapping between domain names and IP addresses, allowing users to access the Internet more conveniently without having to remember the IP number string that can be directly read by the machine. DNS can be divided into authoritative DNS and recursive DNS according to its functions. The authoritative DNS is a server that is authorized by the upper level to resolve domain names. At the same time, it can delegate the resolution authorization to others; recursive DNS is responsible for accepting user queries and then The authoritative DNS initiates an iterative query, and finally returns the result to the user. [0003] In the process of recursive DNS iterative query, data needs to be reques...
