Framework for anonymity in IP-multicast environments
C. Grosch · 2002
The importance of the global Internet for conferencing and entertainment increases with the expanding availability of multicast capable networks. As with other applications and services, security concerns in multicast environments become a major topic for the research community. While there are a lot of publications available analysing the problems of group authentication and privacy, the aspect of anonymity in multicast environments has seldom been considered yet. This paper focuses on a fundamental overview of this topic, introduces a concept for providing anonymity for both senders and receivers in a multicast scenario and presents a optimisation concept for the system.
