A Mix of Role and Task-Based Access Control Model Research

Analysis of role-based access control model and role-based access control model shortcomings,this article presents a mix of roles and tasks based access control model(R-TBAC). In the R-TBAC, this article describes in detail about the assignment relationship between the user, roles, permissions, permits and other elements and the model dynamic and static constraint rules, to ensure that such a hybrid access control method is effective. At last, take the device management system in ERP in the information access as example, R-TBAC model can be used to ensure the feasibility of access to information in the process.
