| Abstract: | With cloud computing widely used in the Internet,problems in role-based access control or RBAC model are gradually exposed.In this paper,Cloud-RBAC model not only adds in the traditional RBAC model temporal constraint parameter,but also adds time effect function CloudDA,role of leasing function CloudTA and permissions lease function CloudTB.It solves the problems about timeliness,permissions and the role delegated in the RBAC model. |
