This paper analyses the cross-organization, dynamic, cooperative and multilevel characteristics of access control problem in grid, and proposes a novel VO-based access control framework. The multilevel access control model is introduced for multilevel requirements and delegation concept is also introduced for permission delegation across organizations.
