一种基于静态和动态信任的普适环境信任模型

针对普适环境中现有信任模型对信任证据的考虑存在片面性的问题，在分析四种信任证据的基础上，将信任分为静态和动态两种类型，并提出了一种基于该分类方法的信任模型，描述了该模型的工作机制。该模型克服了对信任证据考虑不完整的缺陷，有利于在普适实体之间建立起可靠的信任关系，提高系统的安全性。

Developing model for pervasive computing environments based on static-dynamic trust

To resolve the limitations in the integrality of evidence used for the trust judgment in pervasive environments, a new trust model was proposed based on the analysis of the four trust evidence. In this model, the trust was classified into two groups: namely static trust and dynamic trust. Furthermore, the workflow of the model as well as the method of updating trust was described. By using this model, the reliable trust relationship can be set up between pervasive entities, which can enhance the security performance of the pervasive environments.
