摘要
网格安全体系结构GSI保障了网格环境的安全认证和安全通信,它为网格环境提供了一系列的安全协议、安全服务和命令行程序。它在实现时过程比较复杂,一般的建模图只能描述它的主要过程和静态特征,难以分析其动态特性及细节。Pr/T网能够直观地描述非确定性,以图形化的方式表示及运用数学工具模拟与分析复杂系统。利用Pr/T网的这些特性来描述和分析网格安全体系结构GSI中的任务提交与执行过程。
Security certification and security communication are ensured by GSI in the GRID. GSI provides a series of security agreement.security service and command program. Because of its difficult execution process, only main process and static traits are described by ordinary modeling graph. Therefore, it is difficult to analyze the dynamic traits and details. The Pr/T net can describe nondeterminability intuitionistically, which can simulate and analyze complex system through mathematics. The authors have taken advantage of these properties of the Pr/T net to depict and analyze the submission and execution process of assignment in GSI.
