【摘要】 提出一个基于角色的工作流访问控制模型。模型的基本思想:由于工作流中的任务分别对用户和权限进行授权。考虑到任务对授权用户和授权权限的不同要求,采用两种不同粒度的角色分别作为这两种授权的中介。然后,提出一个三层的Wsession结构来控制工作流的运行并给出相关的算法。更多还原

【Abstract】 A workflow access control model based on role is proposed.The basic idea of this model is that users and permissions are authorized by the task of workflow.As the task has different demands for the authorized users and permissions,two kinds of roles differing from granularity are used for either granting authorization.A three-layer structure and some algorithms are proposed for workflow control.更多还原
