| Popis: | This paper summarises ongoing research and recent results on the development of flexible access control infrastructure for complex resource provisioning in Grid-based collaborative applications and on-demand network services provisioning. The paper analyses the general access control model for Grid-based applications and discusses what mechanisms can be used for expressing and handling dynamic domain or process/workflow-related security context. Suggestions are given on what specific functionality should be added to the Grid-oriented authorization frameworks to handle such dynamic security context. As an example, the paper explains how such functionality can be achieved in the GAAA Authorization framework (GAAA-AuthZ) and GAAA toolkit. Additionally, the paper describes AuthZ ticket format for extended AuthZ session management. The paper is based on experiences gained from major Grid-based and Grid-oriented projects such as EGEE, Phosphorus, NextGRID, and GigaPort Research on Network. |
