Abstract

The invention provides a baseband chip, a mobile terminal and a method for authentication of the mobile terminal. The mobile terminal comprises the baseband chip. The mobile terminal further comprises a safety storage module and an authentication processing board card module, wherein the safety storage module is arranged in the baseband chip and saves core confidential data used for user authentication in advance, and the authentication processing board card module is used for reading the core confidential data from the safety storage module when the mobile terminal is powered on so that authentication can be conducted. The user network access authentication function is achieved through the mobile terminal in the mode of software, and the security of user data can be guaranteed.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a baseband chip, a mobile terminal and a method for the mobile terminal to implement authentication. Background technique [0002] In the wireless communication network, the user card and the mobile terminal together constitute a user terminal that provides communication services and information services to customers. The user card plays an irreplaceable role in the field of wireless communication by virtue of its own secure storage, portability, and low cost. The user card is called SIM (Subscriber Identity Module) card in the GSM environment of the Global System for Mobile Communications; it is called USIM (Universal Subscriber Identity Module, Global Subscriber Identity Module) card in the 3G network; UMTS (Universal Mobile Telecommunications System, universal The mobile communication system) environment is called UICC (Universal Integrated Circuit Card), which is a...
