Terminal identification method, and method, system and apparatus of registering machine identification code

A method of registering a terminal machine identification code, the method comprising:

• receiving a registration request, the registration request including a machine identification code of a terminal;
• verifying the machine identification code;
• allocating a machine identification code identifier to the machine identification code if the machine identification code is verified to be legitimate;
• conducting a signature for information that includes the machine identification code identifier;
• and
• sending the signature or a certificate including the signature to a party of the registration request.

A terminal identification system comprising:

• a receiving module used for receiving requests from a terminal;
• a first verification module used for, after the receiving module receives a first request for which signature or certificate verification is to be performed from the terminal, obtaining and verifying a signature or certificate of a trusted party for a machine identification code identifier of the terminal from the first request, wherein the machine identification code identifier is an identifier allocated by the trusted party to the machine identification code of the terminal;
• and
• an identification module used for identifying the terminal using the machine identification code identifier obtained from the signature or certificate after the first verification module verifies that the signature or certificate is legitimate.

A trusted party comprising:

• a receiving module configured to receive a registration request, the registration request including a machine identification code of a terminal;
• a verification module configured to verify the machine identification code;
• an allocation module configured to allocate a machine identification code identifier to the machine identification code when the verification module verifies that the machine identification code is legitimate;
• and
• an issuing module configured to conduct a signature for information containing the machine identification code identifier, and send the signature or a certificate containing the signature to a requesting party of the registration request.
