gSET: trust management and secure accounting for business in the grid

We developed gSET as solution for the unsolved problems in the field of dynamic trust management and secure accounting in commercial virtual organizations. gSET establishes trust and privacy between entities in a grid environment by adapting the concept of secure electronic transactions (SET) used for electronic credit card transfers in eBusiness. Trust is necessary for grid participants in a business environment. It is also necessary to support the dynamic manner of real markets. As distinguished function, in opposite to existing mechanisms as GSI/CAS/VOMS, gSET allows the user to obtain access to a service without disclosing his credentials to the service provider. This minimizes the service provider´s administrative effort needed for user account management. gSET consists of grid services implemented with WSRF/GT4. gSET is an enabling step to make grids a platform for commercial workflows.
