摘要
与传统网络环境相比,网格计算环境提出更高更广泛的安全需求。本文通过对现有网络计费系统进行了分析和设计,提出了一种基于安全体系的网格计费系统的设计方案,该方案不仅能够满足网格环境下各种基本安全需求,而且还能提供具有良好可扩展性的灵活的认证、授权及访问控制机制。本文讨论了一个具体的模型及其实现策略,分析了该计费系统中的一些关键问题和难点,最后对该系统的性能作了简要评测。
In contrast to traditional network environment, Grid environments have a more broad rang of security requirements. A security architecture based grid accounting system is developed. The scheme addresses most of Grid security requirements, provides Grid security solutions, presents a flexible policy based access control mechanism and support scalability to large number of resources and users. The paper introduces the design and implementation of a grid accounting system. Discusses its main problems and difficulties, also gives the solution to these problems.In the end, the performance of the system is estimated briefly.
