What is Fine-Grained Access Control in the Chirp Distributed File System about?

Although the distributed filesystem is a widely used technology in local area networks, it has seen less use on the wide area networks that connect clusters, clouds, and grids. One reason for this is access control: existing filesystem technologies require either the client machine to be fully trusted, or the client process to hold a high value user credential, neither of which is practical in large scale systems. To address this problem, we have designed a system for fine-grained access control which dramatically reduces the amount of trust required of a batch job accessing a distributed filesystem. We have implemented this system in the context of the Chirp user-level distributed filesystem used in clusters, clouds, and grids, but the concepts can be applied to almost any other storage system. The system is evaluated to show that performance and scalability are similar to other authentication methods. The paper concludes with a discussion of integrating the authentication system into workflow systems.
