SUBSCRIBER IDENTITY MODULE-BASED AUTHENTICATION OF A WIRELESS DEVICE AND APPLICATIONS STORED THEREON

摘要

An approach is provided for performing a device-level and/or an application-level security check of a device. In the device-level check, a device hash is generated based on a subscriber identity module identifier (SIM ID), a device identifier, the number of secured applications, and the names of the secured applications. A temporary device hash is generated during a booting of the device. If the device hash is determined to not match the temporary device hash, the applications are removed from the device during the booting of the device. In the application-level check, an application hash is generated based on the SIM ID, the device identifier, and the application name. A temporary application hash is generated during a loading of the application. If the application hash is determined to not match the temporary application hash, the application is removed from the device without running the application.

主权项

1. A method of authenticating a device, the method comprising the steps of:
prior to a process of booting the device, a computer generating a device hash based on a subscriber identity module identifier (SIM ID) of the device, an identifier of the device, a number indicating a count of one or more applications secured in an application registry of the device, and one or more names of the one or more applications secured in the application registry; the computer generating a temporary hash for the device during the process of booting the device; the computer determining whether the device hash matches the temporary hash for the device; if the device hash matches the temporary hash for the device, the computer completing the process of booting the device; and if the device hash does not match the temporary hash for the device, the computer removing the one or more applications from the device during the process of booting the device.
