Mobile Broadcast DRM Based on User Identity Card

The current mobile broadcast systems do not provide efficient solution for consumption of service and content based on the user identity card such as a smartcard. This prevents users from consuming broadcast service and contents independent of a specific terminal (e.g., the one used for registration or purchase). To provide usage of broadcast services based on the user identity card, mutual authentication needs to be established among the service provider, the terminal, and the user identity card whenever the terminal is changed.
