Abstract: With the research of large scale distributed systems, the dynamic trust management of open network environment has become a prominent problem. By analyzing the characteristics of trust relationship in the dynamic environment, this paper gives a dynamic trust evaluation model of distributed environment with fuzzy logic knowledge. This model considers the ambiguity and subjectivity of trust, using fuzzy logic method to get the direct trust value of nodes. To control the calculation efficiency of the global reputation, this model increases a recommendation node information table in this model.
