摘　　要：综合实体状态和行为因素,提出一种可信网络动态信任模型。通过进行实体的状态行为关联分析,提取信任信息,深入分析信任与状态和行为之间的关系,并提出基于状态行为关联的实体动态信任计算方法。仿真表明,所提出的信任模型提供实时动态信任,能够有效地发现和处理动态恶意实体策略性的行为改变和恶意攻击。为网络安全机制制定智能安全策略提供一定参考,提高网络可信性能。Intergrated the factors that state and behavior of entities,a new dynamic trust model of trusted network was proposed.The trust information was obtained through the associated analysis of state and behavior of entities.The rela-tion of trust,state and behavior of the entities was also studied,and a new dynamic trust measurement of trusted network was proposed.The simulation results show that the new trust model has advantages in providing real-time dynamic trust.It is highly effective in countering malicious entities regarding strategic altering behavior and malicious attack,presenting better choice in task assignment in the network,providing help to make the secure police for the network security,and enhancing trustworthily of network.
