物联网环境下域间实体信任评估模型

Inter-Domain Entity Trust Assessment Model in the Internet of Things Environment

针对域间实体在进行资源交互时的信任度统一评估的问题,提出一个物联网环境下域间实体信任评估模型(EIAM)。首先计算域信任度,在不会影响各信任域内实体评价的情况下,根据目前物联网环境下域间实体特性分析,选取参数进行域间实体的信任评估。最后,结合上下文服务环境参数及域信任度,计算处于不同上下文服务环境中的域间实体信任度,解决了域间实体信任度统一评估的问题。

In order to solve the problem of unified evaluation of trust between domain entities in resource interaction,an inter-domain entity trust assessment model of the Internet of things environment(EIAM)is proposed. Firstly,the domain trust is calculated. Under the condition that the evaluation of entities in each trust domain is not affected,the parameters are selected for the trust assessment of inter-domain entities based on the analysis of inter-domain entity characteristics in the current Internet of things environment. Finally,the problem of unified evaluation of inter-domain entity trust is solved by calculating inter-domain entity trust in different context service environments based on the context service environment parameters and domain trust.
