基于D-S证据理论的多维度信任评估方法
Multi-Dimensional Trust Evaluation Method Based on D-S Evidence Theory
摘要
Abstract
A multi-dimensional trust evaluation method based on D-S evidence theory is proposed to evaluate the trust value of cloud service provider in view of the multi-dimensional attributes and uncertainties of trust assessment in the current cloud envi?ronment. The trust relationship between entities is divided into trust,distrust,and uncertain,and the trustworthiness is calculated based on the attribute evidence associated with the cloud service provider. According to the recommendations of third-party entities to calculate indirect trust,and finally direct trust and recommended trust are integrated to assess the entity's comprehensive trust. The analysis of experiment shows that the trust model can be more accurate to make a trust evaluation,so as to effectively prevent malicious attacks. At the same time,the D-S evidence theory is introduced into the direct trust evaluation of the entity,which solves the problem of uncertainty.关键词
