Abstract:
To maintain the global consistency of the authorizing is a challenge when the system authorization is changed in grid environments. This paper proposes a policy-based automatically negotiating method to deal with this issue. An effective system framework, which includes the certificate management, the access policy repertory, the negotiator and the automatcally negotiating mechanism, is designed and implemented. The experimental results show that automated negotiation can quickly regain the global authorization consistency and only cause a little system overhead increasing. Compared with the manual authorization maintaining, the presented method can reduce the negotiating time significantly, and reduce the meaningless grid jobs because the inconsistent privileges are controlled timely.
