摘　　要：网络安全存在的隐患促使网络更多地依靠网络监测来增强控制能力。针对监测结果是否可信以及如何提高网络监测的可信度问题,引入可信计算的思想,提出基于IA分布式网络系统的可信监测算法。通过对监测延迟及网络节点的状态突变参数的提取和分析,可信预测节点状态。仿真结果显示,监测可信因子并不会随节点状态的突变而产生很大波动,表明此算法具有较好的鲁棒性,为系统的通信、分布式任务的执行提供了可信的状态分布图。In order to increase the control capability of network system, it is essential to have a network monitoring which can greatly improve its reliability and stability. To improve the reliability of network monitoring, a trusted monitoring algorithm in IA distributed system with trusted computing technology is proposed. The monitoring delay and mutation parameter of node states are extracted and analyzed. The node states can be predicted trustily and trusted monitoring can be realized. The experimental results are shown that when node states are changed, it validates the good robust of algorithm. A trusted nodes states map for system communication and execution is provided.
