APPLICATION REVOCATION USING AN APPLICATION REVOCATION LIST IN A PORTABLE ELECTRONIC DEVICE

摘要

A portable electronic device (110) contains an application revocation list (ARL) in memory (135) comprising at least one application identifier (AI) uniquely identifying an application. The portable electronic device also contains an application list memory (133) for storing at least application identifiers for trusted applications in the device. A processor (120) operatively connected to the memory determines whether an application identifier on the application revocation list matches an application identifier on the portable electronic device, and, if so, processes a revocation of the application. The application revocation list can be wirelessly updated. Application software in a portable electronic device can thus subsequently be revoked through operation of this application revocation list. A remote server (140) makes application revocation lists available to portable electronic devices over a network such as a cellular system.
