A doh-based electronic device dynamic access method, device and storage medium

Abstract

The present invention proposes a DOH-based electronic device dynamic access method, device and storage medium, the method comprising: a registration step S101, the first electronic device registers its first IP address in the cloud IP address database; the dynamic access step S102. The second electronic device accesses the first electronic device by using the first IP address to which the dynamic network tunnel IP address is mapped based on DOH, and the second electronic device is located in a network different from that of the first electronic device. . In the present invention, when accessing an electronic device on a network (such as an intranet) through a device outside the network, the DOH-based mapping of the dynamic network tunnel IP address to the intranet IP address of the electronic device located in the intranet to be accessed is used Access, because the network tunnel IP is dynamic, thereby avoiding the risk of domain name hijacking, ensuring user data security, protecting user privacy, realizing safe cross-network device access, and improving user experience.

Description

technical field [0001] The present invention relates to the technical field of computer network security access, in particular to a DOH-based electronic device dynamic access method, device and storage medium. Background technique [0002] At present, a browser initiates a network request through a domain name, and the DNS server resolves the domain name into an IP address in order to send the request to the correct IP address. For example, a basic network method in the prior art is as follows: [0003] 1. The user initiates a network request through the domain name in the browser, the DNS server parses the domain name into an IP address, and the browser checks whether there is an IP address corresponding to the domain name in the cache. This cache has an expiration time, usually a few minutes to a few hours. not wait. [0004] 2. If the browser cache is not there, then check the hosts file of the operating system. [0005] 3. If it is not configured locally, it will initi...

Problems solved by technology

[0015] However, some Internet providers (ISPs) intentionally use DNS hijacking techniques to provide error messages when a user enters a URL that cannot be resolved

Once the ISP intercepts this content, it will direct users to its own website, where it promotes its own or third-party products, which seriously affects the user experience. What's more, if the interceptor is a Trojan horse, it may affect system security.

[0016] In addition, the traditional DNS resolution is static. When the network environment fails or data is lost during transmission, the access address cannot be dynamically switched, resulting in an error. Moreover, in the prior art, it is impossible to directly access different DNS addresses through the intranet IP address. electronic devices in the network
