Cacheable Decentralized Groups for Grid Resource Access Control

Sharing data among collaborators in widely distributed systems remains a challenge due to limitations with existing methods for defining groups across administrative domain boundaries with various file systems. Groups in traditional systems are bound to particular domains or file systems using centralized storage locations either beyond ordinary users' ability to manage, inaccessible outside a closed system, or both. The authors present a method for users to independently create and manage groups on any networked workstation using global user identities and to control access to shared data and storage resources based on group membership, regardless of domain boundaries or underlying file systems.
