To solve the security problem introduced by instability and uncertainty existing in grid environment,a trust model based on grey fuzzy multiple attribute group decision-making was proposed.Both the fuzziness and uncertainty of trust relation between grid nodes were considered in the model,factors impacting recommendation credibility between neighbor nodes were analyzed and a logical search strategy for dynamic decision-making group was presented,which can evade malicious nodes directly in the process of searching and ensure that decision-makers would make honest assessment for resource nodes.Furthermore,the weight for each decision-maker is calculated by using advanced D-S theory of evidence,and the assessment results given by decisionmaking group are synthesized using operations of interval grey linguistic variable.Finally,an illustrative example shows the effectiveness of the trust model.
