The invention discloses a terminal authentication method and a smart card. The method includes: when the smart card is connected to the terminal for the first time, after the authentication is successful, storing the identification code of the terminal connected for the first time; if the smart card is connected to the terminal again, the smart card Acquiring the identification code of the terminal accessed at the current moment; judging whether the identification code of the terminal accessed at the current moment is the same as the identification code of the terminal accessed for the first time, and if not, when performing network authentication, send a message to the network side based on the error authentication Authentication parameters generated by authorization information. In the present invention, when the smart card determines that the terminal connected at the current moment is not the terminal connected for the first time, the wrong authentication parameter is sent to the network side to make the network side determine that the smart card has failed authentication in the terminal connected at the current moment, preventing The purpose of using the smart card in other terminals after the smart card is lost or "stolen".
Description
technical field [0001] The invention relates to communication technology, in particular to a terminal authentication method and a smart card. Background technique [0002] With the development of communication technology, communication terminals (such as mobile phones) continue to be multi-functional, and the communication methods are more flexible, which provides convenience for people's communication. In practical applications, communication terminals need to be connected to the network for use. During each access process, such as making / receiving calls and sending and receiving short messages, the network side must authenticate the access terminal (communication terminal). To prevent illegal terminals from accessing the network. The authentication of the access terminal on the network side is realized by authenticating the smart card (SIM card or UIM card) connected to the terminal. When the network side authenticates the smart card successfully, the network side allows ...
