Abstract. Researchers have made much progress in designing secure
and scalable protocols to provide speci c security services, such as data
secrecy, data integrity, entity authentication and access control, to mul-
ticast and group applications. However, less emphasis has been put on
how to integrate security protocols with modern, highly e∆cient group
communication systems and what issues arise in such secure group com-
munication systems. In this paper, we present a exible and modular
architecture for integrating many di erent authentication and access con-
trol policies and protocols with an existing group communication system,
while allowing applications to provide their own protocols and control
the policies. This architecture maintains, as much as possible, the scala-
