The wide acceptance of the grid technology has created pressure to add some features that were not part of its original design
such as security
privacy
and quality-of-service support.In this paper
we have proposed the enhanced grid security and privacy(EGSP) system architecture including EGSP system model
identity protection system
onion routing system
reputation system
and security technology.We also present a network simulation of the model and analyze its scalability.
