The open environment poses the unique security challenges to access control mechanism due to its distributivity, inherent heterogeneity and highly dynamic nature. Attribute-Based Access Control （ABAC） approach can provide flexibility, scalability and fine-grained access control to identity-based access control methods. Its appropriateness for this environment has been proven. In this paper, attribute-based access control mechanism, implementation architecture, and attributes management were discussed. By comparing and analyzing the key technologies, future research issues were suggested.
