Task Delegation-Based Access Model in Distributed Environment
Virtual enterprise is a kind of distributed environment in which the members need to dynamically collaborate each other. An access model is essential in order to control the access to shared resources among member enterprises in a virtual enterprise. We researched the existing traditional access models, which serve the single enterprise and collaborative environments. By incorporating trust management with layer based access control (LBAC) and task based access control (TBAC), we put forward a Task Delegation-based Access Model (TDBAM). In TDBAM,member enterprises are connected by task assignments.Using delegation logic the inter-organizational control rules are enforced among member enterprises. Thus we can protect the resources of each enterprise in distributed environment efficiently and flexibly. And the needs of access control among enterprises are met.
