Abstract

Trust is an important guarantee for information security. According to the uncertainty and dynamic nature of the subjective trust evaluation, it is difficulty to describe the subjective trust with precise language. In this paper, the weight index of factors was quantified by Analytic Hierarchy Process (AHP). In view of fuzzy set corresponding with subordinate function, imitating the normal distribution function in probability theory, a subjective trust model based on fuzzy neartude was proposed. Finally, example analyses verify that the presented approach is feasible and effective.
