Embodiments of the present invention provide a method for security authentication of user identification card lock data and a mobile terminal. Wherein, the method includes: physically fusing the corresponding register bits in the fuse register of the user identification card lock data corresponding to at least one operator stored in the mobile terminal code storage area, so that the user identification card lock data The corresponding register bit enables; if the data of the operator of the subscriber identification card is consistent with the subscriber identification card lock data corresponding to the enabled register bit, then the subscriber identification card lock data in the code storage area is adopted The secure boot mechanism performs security authentication. The embodiments of the present invention can protect the operator's user identification card lock data from being cracked and tampered with, and improve the security of the user identification card lock data.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular to a method for security authentication of user identification card lock data and a mobile terminal. Background technique [0002] The function of subscriber identity module lock (Subscriber Identity Module lock, SIMLOCK) is that the mobile phone operator restricts other operators' subscriber identity card (Subscriber Identity Module, hereinafter referred to as: SIM) card or global subscriber identity (Universal Subscriber Identity Module, hereinafter referred to as: USIM) card in the mobile phone it operates. A function used on the Internet is a way to bind the mobile phone with the operator, that is, the mobile phone with SIMLOCK information can only use the SIM card of the operator specified in SIMLOCK, otherwise it needs to enter a password to use, thus protecting Carriers perform specific services. [0003] SIMLOCK information store...
