Abstract
A mobile station is configured to authenticate applications running thereon in order to control access by the authenticated applications to secure data stored in a subscriber identity module of the mobile station. Sensitive data securely stored in the subscriber identity module is associated with one of multiple personas implemented on the mobile station. When an application running on the mobile station requests access to the secure data, a secure domain controller processes the request and authenticates the application, for example based on an application authentication key. The secure domain controller further determines whether the application is associated with the same persona as the secure data identified in the request. If the application is authenticated, the secure domain controller then allows the application to access secure data associated with the same persona, but prevents the application from accessing secure data associated with other personas.
