Research on access control in grid environment

Role-Based Access Control, for short RBAC, is a security technology that ensures system resources can not be accessed by non-authorized users. It can be used in network security and works well for grid security as well. Based on the research of RBAC model at present the paper proposes a role-based access control model in grid environment. The model still discusses the issues of role authorization rules, permission conflict, and global authorization and so on. At the same time, the related formal description is given. The future work is to realize the model and implement the related system in specific project. Index Terms — grid, access control, RBAC, role authorization, permission conflict
