This prevents users from consuming broadcast service and contents independent of a specific terminal . 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. The crucial element for this is assuring the service provider the terminal and the user identity card by authenticating each entity to the other entities. In this paper we propose the new authentication scheme which provides efficient scheme for three kinds of mutual authentications among the service provider the terminal and the user identity card. We also construct mobile broadcast DRM system based on the proposed authentication scheme for consumption of broadcast services with multiple terminals. Copyright 2007 Byung-Rae Lee.
