User Credential based Role
mapping in multidomain environment
Abstract: The administration of access rights of service in multi-domain environment is a complex and challenging task. In particular, Web Services and Grid based systems are emerging systems in multi-domain environments. However Role-base access control (RBAC) is a powerful concept as it supports uniform representation of security policies. So RBAC can be effectively used in such environments. We propose user credential based approach for merging RBAC policies of multiple heterogeneous organizations.
