介绍了基于角色的访问控制模型和基于任务的访问控制模型的原理。
This paper introduces the theory of access control model based on role and task, and analyzes task and the shortage of above models.
基于任务的访问控制模型是一种以任务为中心，并采用动态授权的主动安全模型。
Task based Access Control Model is task centered and offers dynamic authorization , so it belongs to the active security model.
提出了一个数字证书营运中的基于任务的访问控制模型，解决了数字证书营运中的安全问题。
In this paper, we develop a task-based access control model for the service of certificate to solve those secure-problems.
访问控制技术是网络安全的一项基本技术，主要包括基于角色的访问控制和基于任务的访问控制等技术。
Access control is a basic technology in network security. It includes the role based access control and the task based access control, etc.
而基于角色的访问控制模型以角色为中介，将用户与权限逻辑隔离，但该模型不能处理有执行顺序的任务；
Role is introduced to separate user and privilege in role-based access control model, but RBAC can't directly control the permission for a sequence of events.
最后，对该方法在主动式的基于任务访问控制中的应用进行了探讨。
The application in active task-based access control of the method is also discussed in the end.
