Based on Expand RBAC Grid Collaborative Design System Access Control Model

The access control is the multitudinous computer security solution one kind, also is the most direct-viewing most natural one kind of plan, but based on role access control (RBAC) is the most influential high-level access control model, however, as a result of the grid cross organization, the tendency, isomerism characteristic, established the access control in the grid coordination design system also to need to carry on the expansion to RBAC, this article has made the simple introduction to RBAC, and has analyzed it under the grid environment insufficiency, gave one kind based on to expand RBAC the grid coordination design system access control model, in did not reduce the autonomous domain in the safety control efficiency situation, could realize the virtual organization. The fine grain is authorized and guarantees the autonomous domain the security policy not to destroy. And the confirmation has been carried on under the experimental grid environment.
