A semantic trust model of large scale distributed system based on Ontology

With the in-depth research of large-scale distributed application systems, the traditional software system ecology has shifted from closed relative static form to open, shared and publicly accessible dynamic collaborative service mode. The original trust model has been unable to adapt to the identification of new system security problems, so the research of the dynamic trust model has become a hot spot. In this paper, we propose a large scale distributed system trust model (LSDM) based ontology based large-scale distributed system semantic trust model, which aims to describe the interaction behaviors between entities, and give consideration to the sharing and scalability of models. On the other hand, the RBTM trust calculation method is proposed to improve the recognition rate of the model based on LSDM.
