Han Sanga

In the background of Intelligent city, the information system needs resources sharing and cooperative operation, and the traditional access control technology is confronted with new demands and challenges. Based on the RBAC model, this paper introduces the element of "application", which includes different roles and permissions, and realizes the unified authorization by giving the people the roles that belong to different applications. At the same time, the model constraint and model parameter configuration as well as the corresponding conflict detection strategy are proposed, which can effectively avoid and detect the conflicts and ensure the correctness of the authorization by detecting the basic operation of the tree elements, the Role association permissions and the authorization rules.
