Abstract

In this paper we analyze the access control requirements of the dynamic virtual organization in grid environment and define an absolutely decentralized access control mechanism for the dynamic coalition characteristic of virtual organization. The access control framework in the paper combines the threshold BLS signature schema and the role based access control mechanism to provide a flexible and decentralized mechanism for the VO-based grid applications.
