Secure multicast in the broadband satellite multimedia networks

Satellites are expected to play an essential role in providing broadband and multicast services to regions that cannot be economically reached by terrestrial networks, in particular the more remote regions of Europe and the rest of the world. Security can be a problem for such global services. Security of multicast data is becoming an important issue to operators and users of satellite networks. This paper presents a proposed secure multicast architecture that fits well into the ETSI BSM overall architectural concepts. Multicast service scenarios with detailed security architecture are presented using the BSM standard interface between satellite dependent and independent layers. This architecture accommodates link and network layer security (Internet) security systems and interworking with non-satellite entities such as AAA, PEPs and CON entities.
