A Composite Access Control Model Based on Attribute and Role

Abstract

Aimed at the problem of user privacy protection in cloud computing environment, this paper proposes a composite access control model based on attribute androle. The method is a combination of the traditional single access control model. The technology assigns roles based on attribute strategy first and subsequently assigns permissions based on roles, to make the subject operate object by access control. The simulation experimental results show that compared with the traditional single access control model, this model can effectively reduce the leakage of private data under the premise of the efficiency guarantee.
