Abstract
A tamper-resistant security device, such as a subscriber identity module or equivalent, has an AKA (Authentication and Key Agreement) module for performing an AKA process with a security key stored in the device, as well as means for external communication. The tamper-resistant security device includes an application that cooperates with the AKA module and an internal interface for communications between the AKA module and the application. The application cooperating with the AKA module is preferably a security and/or privacy enhancing application. For increased security, the security device may also detect whether it is operated in its normal secure environment or a foreign less secure environment and set access rights to resident files or commands that could expose the AKA process or corresponding parameters accordingly.
