Um sistema de autorização de grade computacional integrado a portais

Vanderlei CostaSilvio Luiz StanzaniHermes Senger

Grid platforms have been increasingly adopted to promote the sharing, aggregation, and coordination of large amounts of geographically distributed and multi-institutional resources. In such environments, which involve large amounts of resources placed at several administrative domains and subject to multiple access control policies, access control is mandatory. As the main contribution, in this paper we extend the GridSphere portal framework, aiming to provide tools and mechanisms for access control which can be used for the development of portal-based grid applications. The mechanisms and tools proposed also enforce access control at the service invocation level, which can be used by any OGSA compliant application which invokes grid services. Our approach allows for the integration and consistency between authorization policies adopted for both portal-based and regular applications.
