摘　　要：针对物联网环境下实体间的跨域信任问题,引入网关技术,提出基于网关的跨域信任模型。将域间节点历史交易纪录存储于网关中,提高对域间节点信任度的计算和存储能力;引入节点信任因子、历史因子,结合上下文环境变化对节点信任度值进行计算;提出节点跨域信任算法,并给出了模型详细流程。实验结果表明,模型具有良好的网络动态适应性以及较高的域间节点交互成功率,降低了物联网环境的变化对跨域节点信任评估准确性的影响。The trust relationship inter-domain is restricted by difference of inner-domain model in Internet of Things, based on the UTM, a new IOT inter-domain trust model is proposed which implements trust value conversion among domains by gateway. In this model, the history scheduling record is stored on gateway by the strong computing and storage capacity. With the trust factor, history factor and context, the node trust value is computed, and then the trust algorithm of inner-domain is described. Finally, the process step of trust model is given. The experiments show that the model is efficient on SSP when IOT full load and stabilization, reduce the passive affect of veracity inter-domain trust value.
