A method of preventing dns from being hijacked by using encrypted signature and accelerated analysis

Abstract

The invention particularly relates to a method for preventing DNS from being hijacked by adopting encrypted signature and accelerated analysis. The method of using encrypted signatures and accelerated resolution to prevent DNS from being hijacked, using digital signatures to authenticate and encrypt the DNS resolution process, setting the TTL value, and increasing the cache hit rate of domain names; using DNS‑prefetch to allow DNS pre-reading to split DNS domain name resolution Increase parallel downloads for multiple domain names, speed up DNS domain name resolution, and then achieve the purpose of preventing DNS from being hijacked and speeding up DNS resolution. The method of using encrypted signature and accelerated resolution to prevent DNS from being hijacked, using encrypted signature authentication and setting TTL values ​​appropriately to prevent DNS from being hijacked, speeding up DNS resolution, greatly improving the ability of users to access websites that are blocked and redirected to non-purpose websites and The problem of slowing down the website access speed.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method for preventing DNS from being hijacked by using encrypted signatures and accelerated analysis. Background technique [0002] In the era of computer network technology, DNS (Domain Name System, Domain Name System) hijacking means that the hijacking party intercepts the domain name resolution request in a certain network, returns a wrong IP address to the requesting party or does nothing to make the request unresponsive, resulting in Cannot access a specific website or return an error URL, also known as domain name hijacking. [0003] For the problem of DNS being hijacked, several solutions have emerged: [0004] 1. Use blockchain technology to enter DNS data into the chain, verify it from the App side, combine it with local DNS, and use the consensus mechanism of blockchain to solve the DNS security problem on individual user routes; [0005] 2. On the mobile ...

AI Technical Summary

Problems solved by technology

[0007] Although the above methods can avoid the problem of DNS being hijacked, the several DNS anti-hijacking methods prolong the DNS request processing time to a certain extent

In the era of rapid development of information technology, users have certain requirements for the response speed of the website. If some methods are used to prevent DNS from being hijacked, the response speed of the website will be reduced, which is not advisable.
