Abstract

The massive deployment of IP multicast-based services raises important issues, as far as the security is concerned. In particular, there is a growing need for ISPs to be able to provide some guarantees with respect to the identification and authentication of sources and receivers, not to mention the preservation of the confidentiality of the traffic that will be forwarded along the dynamically computed distribution trees. In this paper, we propose a generic scheme where service providers will play a key role for the provisioning of secure IP multicast services, based on the ongoing standardisation effort being conducted within the msec working group of the IETF. A first part relates to cryptographic services, e.g. data authentication and encryption, and highlights the role a telecom operator could play in securing group communications. In particular, various opportunities for providing GCKS (Group Controller and Key Server) services and cryptographic treatment services, are discussed depending on the targeted market and the use made of the deployed IP multicast network. A second part emphasizes the opportunities offered by multicast content security and the associated key management, to perform accounting. The way a telecom operator could take advantage of such possibilities in order to offer value-added services is discussed. Various accounting and billing models, made possible by the msec facilities, are demonstrated.
