Abstract
A user equipment (UE). The UE comprises a memory module, wherein the memory module is one of a subscriber identity module (SIM), a universal integrated circuit card (UICC), a universal subscriber identity module (USIM), or a removable user identity module (R-UIM), wherein clock signals from a second clock component are input to the memory module. The memory module comprises an application stored in a trusted security zone in the second non-transitory memory, that when executed by the second processor in the trusted security zone, wherein the second operating system accesses the second processor to implement instructions for applications in the second operating system, wherein the trusted security zone provides hardware assisted trust, compares a first mobile equipment identifier (MEID) stored in the first non-transitory memory with a second MEID stored in the memory module.
