Research on Security Architecture Model of Grid Computing System

This paper analyzes security problems existing in Grid Computing System,describes the consideration of security mechanism of Grid Computing System. A more comprehensive and flexible security architecture model of Grid Computing System has been proposed on basis of explosion of GSI(Grid Security Infrastructure) adopted by Globus. Compared with GSI,resource mapping and management are characteristic of the new model. A security schema then has been brought into effect under the Globus environment based on this security architecture model. Future works are introduced in the end.
