Using network authentication to counter subscriber identity module card man-in-the-middle subsidy lock attack

Abstract:

A method, telecommunication apparatus, and electronic device for securely using a subscriber identity module are disclosed. A secure memory 308 may store a secure international mobile subscriber identity. A subscriber identity module interface 312 may receive an unlocking international mobile subscriber identity. A processor 304 may erase a cache temporary mobile subscriber identity if the unlocking international mobile subscriber identity does not match the secure international mobile subscriber identity.

Abstract(Chinese):

公开了一种用于安全地使用用户识别模块的方法，电信设备和电子设备。安全存储器308可以存储安全的国际移动用户身份。订户身份模块接口312可以接收解锁的国际移动用户身份。如果解锁的国际移动用户身份不符合安全的国际移动用户身份，则处理器304可以擦除高速缓存临时移动用户身份。
