网格是未来分布式计算的主要发展方向,而网格安全不仅是网格推广应用的前提,也是计算网格中的一个核心问题。通过对网格安全需求进行分析,从不同角度观察网格安全,抽象出网格安全模型的物理视图和逻辑视图。重点研究了网格环境中访问控制策略与授权策略。结合网格安全项目的研究,设计并实现了利用网格安全认证、访问控制策略进行P2P分布式计算的应用实例。
Grid is the main developing direction of future distributed computing. Grid security is not only the premise of grid wide application, but also one of the main problems of computational grids. Through analysis of the need of grid security, checking grid security by different aspects, the physical and logic views of grid security model were presented. Then the access control policy and authority policy of grid computing was emphatically researched. At last, an application instance of P2P distributed computing with grid security certification and access control policy were designed and implemented by combining with the research project of grid security.
