Abstract
This paper presents an authorization solution for resource management and control developed as part of the China Education and Research Network (CERNET) to perform fine-grained authorization of job and resource management requests in a Grid environment which meets the Fusion-Grid’s security needs in large scale networks such as CERNET. It integrates the GT2 job manager and X.509 authorization and this model can be extended to other authorization decision functions. It allows the system to evaluate a user’s resource specification language request against authorization policies on resource usage. Furthermore, based on XML integrated authorization policies, it allows other virtual organization members to manage the user’s resources.
