摘要：In order to determine the conditions for the application of the dynamic authorization problem in the Internet of things, a reliable trust mechanism must be established between the institution, the reader and the tag. Thus, this paper proposes a hierarchical trust mechanism, and puts forward a verifiable caching interaction digest schema at the same time. At first, this paper analyzes the features of the application and the trust demands of different subjects in the Internet of things, the credibility of the detaching mechanism and the reader trust. Then, it proposes the improved method of evidence theory accoording to the characteristics of the readers, which can deduce the routing trust of the reader. The experimental results show that the hierarchical trust mechanism has a very good convergence of trust, and the algorithm in this paper can effectively detect the malicious terminal nodes.
