Abstract

Abstract: To control the workflow in workflow system，a workflow controllability model based on tasks and roles is proposed.The model introduces the concept of tasks in role-based access control model，and adds a property of time constraint to task.Permissions are dynamic assigned to the task according to its needs by dynamic authorization in the mode.

Key words: role, task, access control, workflow

摘要： 对于工作流系统中的工作流控制，提出了基于任务和角色的工作流访问控制模型。模型在基于角色的访问控制模型中引入任务，并为任务的执行增加了时间约束，通过对任务的动态授权实现了权限的按需和动态分配。

关键词: 角色, 任务, 访问控制, 工作流
