摘　　要：入侵容忍是新兴的第三代网络安全技术。针对现有入侵容忍系统模型的不足,以Petri net为建模工具,提出了一种分布式入侵容忍系统的模型,给出了该模型的具体解释,并通过实例详细分析了模型的多个性能。分析结果表明,该模型能够扩展对现有入侵容忍系统的描述范围,同时也细化了对入侵容忍系统各个属性的描述。Intrusion tolerance is the rising third generation technology of network security. For the shortcomings of existing models of intrusion tolerant systems, a model of distributed intrusion tolerant systems is proposed through the tool of Petri net. The concrete interpretation of the model is given, and the performances of the model are analyzed in detail on the basis of examples. The results of analysis show that this model ex tends the description range of the existing intrusion tolerant system and can describe many of the properties of intrusion tolerant systems more particularly.
