A VO-Based Security Architecture for Authentication and Authorization in Grid
Yan Yang, Xingyuan Chen, Bin Zhang, Binglong Li · 2009
A grid system is a virtual organization that is composed of several autonomous domains. Security in such a system needs to be flexible and scalable to support multiple security policies. Basing on the special security requirements of VO-management, we propose a security architecture that can support multiple authentication policies in a VO to provide scalable and flexible VO-wide authentication, role-based, multi-grained authorization for access to and usage of the resources.
