Abstract--- Multicast and anycast have received consider­
able attention due to their ability to support networked ser­
vices. There are distinct and significant security vulnerabili­
ties in both the multicast and anycast model including denial
of service, theft of service, eavesdropping, and masquerad­
ing. The multicast problem requires a secure IGMP. The
anycast problem requires secure anycast server advertise­
ments. We generalize these two problems into a problem of
group access control and propose Gothic, a complete archi­
tecture for providing group access control. Gothic centers
around a novel authorization architecture. This is comple­
mented by a proposal for a group policy management sys­
tem that allows the group owner to be authenticated before
being allowed to specify the group access rights. This sys­
