This paper proposes several integrated security architecture designs for client-server group communication systems. In an integrated architecture, security services are implemented in servers, in contrast to a layered architecture where the same services are implemented in clients. We discuss the performance and accompanying trust issues of each proposed architecture and present experimental results that demonstrate the superior scalability of an integrated architecture.
