讨论了信息网格中的安全需求。在分析网格安全技术的基础上,提出了基于代理的安全策略,并从中抽象出了网格安全的分层模型,该模型的一个主要优点就是能解决可扩展性和可移植性的问题。
Discussed the security requirements in the information grid. Based on the analysis of grid security technology, a proxy-based security strategy is proposed and a hierarchical model of grid security is abstracted. One of the main advantages of this model is that it can solve the problems of scalability and portability.
