This paper presents Worm-IT, a new intrusion-tolerant group
communication system with a membership service and a view-synchronous atomic
multicast primitive. The system is intrusion-tolerant in the sense that it
behaves correctly even if some nodes are corrupted and become malicious. It is
based on a novel approach that enhances the environment with a special secure
distributed component used by the protocols to execute securely a few crucial
operations. Using this approach, we manage to bring together two important
features: Worm-IT tolerates the maximum number of malicious members possible;
it does not have to detect the failure of primary-members, a problem in
previous intrusion-tolerant group communication systems.
