Design of Attribute-Based Access Control Model in Collaborative Grid Environment

摘要：

Grid environment aims to integrate large number of distributed and heterogeneous resources to provide significant computing power, especially across administrative domains. But only in the secure environment the grids can be real fulfilled, especially the access control issues. The traditional RBAC model is facing some troublesome questions in the new collaborative grid environment, such as user-role assignment and mapping difficulty. Attributes, extending from roles, can make up those shortcomings of RBAC, and also make access control more flexible, dynamic and fine-grained. Mela-attribute and meta-policy are presented to describe the attributes and policies in local domains.
