Authentication method and system for mobile communication terminal

Abstract

The invention provides an authentication method of a mobile communication terminal and a system thereof. The authentication method of the invention comprises the steps that: the identifier of the mobile communication terminal, an SIM card identifier and password for a subscriber are first obtained to generate authentication information; the generated authentication information is then sent to an authentication server which carries out the authentication to the authentication information to obtain the authentication result; the authentication result is finally sent back to the mobile communication terminal; the mobile communication terminal judges whether the authentication is successful or not according to the authentication result and the mobile communication terminal can be normally operated when the authentication is successful. In the method of the invention, when the subscriber changes the SIM card of a mobile phone, the authentication of a legal subscriber can be accomplished on the server and an illegal subscriber still fails to use the mobile phone normally even the phone re-burns records. Therefore, the authentication method of the invention can prevent the situations such as the stealing of mobile phones or phone cards, which results in that the mobile phone can be avoided being stolen.
