Domain name encryption method, decryption method, and apparatus based on content delivery network

A domain name decryption method based on a content distribution network, being applied to a domain name system (DNS), and comprising:

• receiving a domain name resolution request sent by a terminal, the domain name resolution request comprising an encrypted synthetic record domain name;
• decrypting the encrypted synthetic record domain name to obtain a domain name resolution result;
• and
• sending the domain name resolution result to the terminal.

A domain name encryption apparatus based on a content distribution network (CDN), being applied to a CDN system, and comprising:

• at least one processor;
• and
• a memory for storing instructions executable by the at least one processor;
• wherein the instructions, when executed by the at least one processor, cause the apparatus to:
• receive an access request for an initial server sent by a terminal;
• acquire, in a case that the initial server needs to be redirected to a target server, a synthetic record domain name of the target server, the synthetic record domain name carrying a domain name resolution result of the target server;
• and
• encrypt the synthetic record domain name to obtain an encrypted synthetic record domain name, and send the encrypted synthetic record domain name to the terminal.
