Abstract
Disclosed is a method for securely presenting content in a mobile station. The mobile station may have a smart module, a security agent, and an air interface for communicating with a content provider and with a remote content rights manager. The smart module stores content presentation units and has a proxy content rights manager for when the mobile station is unable to receive secure content keys from the remote content rights manager using the air interface. In the method, content presentation units are transferred from the remote rights manager to the smart module for storage. Secure content keys are requested from the smart module for allowing presentation of content requested while the mobile station is unable to communicate with the remote rights manager. The secure content keys are transferred, based on a stored content presentation unit, from the proxy content rights manager to the security agent for allowing content presentation.
