Multicast services raise significant operational and security challenges not only when deployed on the Internet layer, but also in overlay networks. Large P2P groups as emerging from IPTV applications may be abused by unwanted traffic or denial of service attacks through amplified flooding.

We present an IBC infrastructure setup phase, a peer registration...
