摘要

Although some trust management approaches are proposed for cloud computing, these approaches only deal with single and simple trust relationship, trust algorithms in these models are one dimensional, and can not accurately measure the trust relationship between multi-users. In the paper we present a cloud trust model based on trust level agreement. The proposed method can assist cloud computing entities to make good interaction decisions. The main contribution of this paper is to provide a hierarchical trust modeling method to user and improve his or her security situational awareness in the cloud computing environments. The experimental results show that the proposed method has a higher trust accurate rate and interaction success rate, and it is qualified to prevent malicious entities attacks while maintaining efficiency. Our analysis shows a significant improvement in comparison to traditional trust management technology. Our work appears to be the first attempt to research the multi-entities trust management method in cloud computing.
