In this paper we propose a trust-based dynamic access control model for cloud computing environment inspired by the GTRBAC model, where the users can validate their legal identities and acquire their access control privileges for the resources according to the role information and the trust-degree in the lightweight certificates. The trust-degree in the certificate can be calculated by the direct trust-degree (DT) and recommendation trust-degree(RT), while the access permission for the resources can be decided by comparing the trust-degree with trust-degree threshold, in order to achieve effective control for cloud computing resource. Our theoretical analysis results show that this method can effectively provide dynamic and secure access control.
