| 摘 要： | 通过对目前入侵容忍系统模型的改进，构建了具有自恢复和自适应特点的分布式自适应入侵容忍系统模型。通过对入侵容忍系统的数据完整性、保密性和系统响应速度的定量分析，提出了响应度的新概念，完善了入侵容忍度（ITD）的概念，并对模型进行了求解和仿真。仿真结果表明，新模型具有更好的完整度、保密度和入侵容忍度，对建立响应时间稳定的、提供连续可靠服务的分布式自适应入侵容忍系统具有积极的指导意义。

| Abstract: | A distributed adaptive intrusion tolerant model with recovery and adaptive characteristics is proposed by improving current model of intrusion tolerant system.The conception of response degree is proposed and the concept of Intrusion Tolerance Degree（ITD） is perfected through quantitatively analyzing intrusion tolerant system data integrity,data confidentiality and system response speed.Simulation and solution are carried out.The results of simulation show that the new model has better integrity degree,security degree and intrusion tolerance degree.It is meaning to design a distributed adaptive intrusion tolerant model that can provide continuous and reliable service with stable response time. |
