An identity-based grid security infrastructure model

Grid security is a wide topic, touching many of the core issues in information security. It is an area that has been overlooked by the established grid community. In this paper, We explore some roles of identity-based cryptography (IBC) in grid circumstance, and propose a grid security infrastructure model based on identity cryptography. We mainly discuss the grid security authentication and authorization architecture, public key infrastructure based on identity cryptography and security group communication scheme by using weil pairing. The security property of our scheme is discussed. Finally, we compare our ID-based security infrastructure with the public key infrastructure in grid circumstance.
