A trust-based cloud computing access control model

摘要

The paper introduces the current status of the research on the trust-based access control model. On the based of the traditional TRBAC model, the paper presents a new trust model where the concepts are introduced, e.g. authentication, trust threshold value and secondary verification, etc. In this paper, the trust value is ranked and a detailed computing method is disclosed for credibility value. When the trust grade is at certain level, the service provider would perform permission granting. The experiment shows that the new model has relatively strong competence to resist malicious attacks.
