采用多种技术集成的方法进行安全工作流管理系统体系结构研究。以工作流管理联盟提出的工作流参考模型为基础,建立一种安全工作流管理系统体系结构。引入基于数字签名的工作流安全认证机制,提出扩展的工作流访问控制模型,并定义了多级安全工作流授权规则。
With the integrated method of many technologies, this paper makes a research of architecture on secure workflow management system. Based on the Workflow Management Coalition (WfMC)'s workflow reference, the paper introduces a new architecture of workflow management system. The mechanism of secure authentication based on digital signature is proposed and then extend workflow system access control model is presented, the multilevel security authorization rules for workflow system are defined respectively at last.
