Top-level domain name management and analysis method and system based on block chain

Abstract

The embodiment of the invention provides a top-level domain name management and analysis method and system based on a block chain. The method comprises the steps that a main node receives request information, transmitted by a request node, for top-level domain name resource recording operation, and packages the information of the main node and the request information passing the verification intoa pre-preparation message for broadcasting; each common node verifies the received pre-preparation message and generates a preparation message for broadcasting after passing the verification, and thepreparation message comprises request information, a request information verification identifier and current node information; and each node verifies the received preparation message, and if the number of the preparation message sending nodes passing the verification reaches a consensus threshold, an operation result corresponding to the request information in the preparation message is added to anew block in the local block chain. According to the method, the security of the top-level domain name resource recording operation stored in the block can be ensured, the top-level domain name hijacking attack is resisted, and the consistency of processing and storing the top-level domain name resource recording operation by multiple nodes is realized.

Description

technical field [0001] The present invention relates to the technical field of computer networks, in particular to a block chain-based top-level domain name management and resolution method and system. Background technique [0002] The domain name system is a distributed database with a hierarchical structure, which can map domain names and IP addresses to each other, so that users can access the Internet more conveniently, without having to remember the IP number strings that can be directly read by the machine. [0003] When a user accesses Internet services through a domain name, the client will encapsulate the domain name to be resolved into a domain name resolution request message and send it to the specified domain name resolution recursive server. After the recursive server finds the IP address corresponding to the domain name through the local cache, it returns the IP address to the client through the domain name resolution response message. If the local cache does ...

Problems solved by technology

[0005] Existing centralized management and resolution of top-level domain names present various security threats: on the one hand, there are security risks of domain name hijacking attacks against top-level domain names. Once a top-level domain name is deleted or modified from the root zone data, users will not be able to pass through the recursive server. Realize the correct resolution of the top-level domain name, which means that the network corresponding to the set of domain names under the top-level domain name will no longer be accessible, or users will be directed to the wrong network address, so that the corresponding network will have the risk of disappearing

On the other hand, the malicious modification of the top-level domain name resource records by the root server administrator will also lead to the risk of disappearance of the corresponding network
