Conditional access to media for mobiles: IP multicast system
2002 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

Conditional access is necessary to provide the broadcast services only to authorized receivers. In current conditional access systems these services are protected by digital scrambling at the MPEG2-transport stream level. The Media For Mobiles - IP Multicast system transports IP-based data using DAB technology. However, there is no functionality how to provide conditional access to IP-based services. In this thesis the possibilities of using IPSec to protect the services and integration of IPSec into the framework of conditional access system are considered. The effective key management schemes for distribution of broadcast services are also a subject of this thesis as well as security for return channel. A good concurrent to the current key management scheme for subscription services is the Tree scheme. This scheme adds flexibility to viewers in choice of services they want and requires less key storage for conditional access system operator. The one-way function chain tree-based scheme allows to provide services like pay-per-view and impulse pay-per-view which are not present in many conditional access systems. Many payment schemes require the provision of return interactive channel from the viewer to the conditional access system operator. To protect communication through the return channel the SSL is proposed.
