Abstract
An IPTV (Internet Protocol Television) technology is the new convergence technology of the telecommunication and broadcasting which provides various bidirectional TV services. To provide these services only to legal subscribers, mutual authentication between set-top box connected with TV set and the smart card owned by a subscriber is needed. In this paper, we propose an attribute-based mutual authentication scheme that only someone who is satisfied with some attributes, such as titles or departments, can access the contents provided by the IPTV service in an organization. We also show that the proposed scheme is secure. Our proposed scheme has a virtue that user can access various services, provided by an organization where he/she belongs to, according to their attributes with only one time registration. As far as we know, this is the first attribute-based authentication scheme which can be applied to any organizations in IPTV environments.
