摘要
对基于可信实时计算基(TTCB)的分布式容侵系统的体系结构进行了研究,针对分布式容侵系统中的一致性问题,实现了利用TTCB服务的容侵原子多播协议。在进程总数大于两倍恶意进程个数的条件下,该协议可以满足正确结果的一致性要求,达到了入侵容忍的目的。最后证明了该协议算法的正确性。
This paper studied the architecture of a distributed intrusion-tolerance system based on trusted timely computing base（TTCB）, and proposed an atomic muhicast 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.
