Domain name resolution method and domain name resolution device

The present invention discloses a domain name resolution method and a domain name resolution device, wherein the domain name resolution method comprises the steps of: transmitting an encryption communication request to a preset domain name resolution server according to pre-stored local certificate public key information; receiving and obtaining a server certificate public key contained in an encryption communication response corresponding to the encryption communication request; performing handshake authentication with the server returning the encryption communication response according to the server certificate public key and the local certificate public key information; and when the authentication is passed, establishing an encryption communication connection with the server which returns the encryption communication response and obtaining a domain name resolution result through the encryption communication connection. Through adoption of the domain name resolution method of the invention, the encryption c
