网格技术的广泛应用对网格环境的安全、隐私和服务质量提出了越来越高的要求.提出了增强网格安全和匿名系统构架,包含系统模型、身份保护系统、洋葱路由系统、信誉系统和安全技术等.并通过计算机网络系统模拟分析了其可扩展性.%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.
