普适计算中信任模型的研究

Research of Trust Model in Ubiquitous Computing

首先概述了现有两种主要的信任模型以及其存在的问题,然后结合不确定概率理论和普适计算的特点,提出了普适环境下一种新的信任模型———基于属性凭证的信任模型。最后给出了它在实际中的应用。

Firstly reviews the two major recently-used trust model and their problems. Then with the knowledge of uncertain probabilities and character in ubiquitous computing, it presents the trust model based on the attribute credential, a new trust model in ubiquitous computing. Finally it puts forward an application of the new model.
