Abstract:In a service grid, the efficiency of security administration and security assurance of virtual organizations and autonomous domains are challenging issues. Access control is usually implemented through mapping virtual organization users to autonomous domain's local users, which reduces the efficiency of security administration and bears the risk of violating security policy of these domains applying RBAC model. A role-based delegation access control model for virtual organizations is proposed in the paper, which has little effect on security administration efficiency, and does not violate autonomous domain's security policy. It is implemented and validated in a grid-based e-Government platform.
Keywords:service grid  virtual organization  access control  role- based delegation  policy
