This paper studied the architecture of a distributed intrusion-tolerance system based on trusted timely computing base(TTCB), and proposed an atomic multicast protocol for intrusion-tolerance using TTCB services to solve the consensus problem in distributed intrusion-tolerance system. When the total of processes is more than twice the number of malicious processes, the protocol can satisfy the consensus and achieve the intrusion-tolerance. It proved the Correctness of the protocol.
