Summary: Scaling Secure Group Communication Systems: Beyond Peer-to-Peer
This paper develops several integrated security architecture scenarios 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 benefits and drawbacks of each proposed architecture and present
