| 1. | A model of task - role based access control and its application
一种基于任务和角色的访问控制模型及其应用 |
| 2. | Researchers have proposed several rbac models , which include the famous rbac96 model
研究人员已经提出若干基于角色的访问控制模型，其中包括著名的rbac96模型族。 |
| 3. | The paper first introduces several typical role _ based access control models , at the same time analyses and compares them
本文首先介绍了几种具有代表性的基于角色的访问控制模型，并对这几种访问控制模型进行了分析比较。 |
| 4. | In this paper , a new model ( osrbac model ) is discussed , which is the improved model to rbac3 model in rbac96 model family
本文对基于角色的访问控制的经典模型? ? rbac96模型族中的rbac3模型进行改进，提出一种新的基于角色的访问控制模型? ? osrbac模型。 |
| 5. | ( 5 ) based on the reference and development of the existing research methods about the correlative research directions ( distributed virtual environment and network - based cad ) , a di
( 6 )针对基于角色的访问控制模型的局限性，提出了一种基于角色与基于规则相结合的访问控制模型( rrbac ) 。 |
| 6. | At the end , we analyzes and compares rbac features supported in the most recent versions of three secure operating systems : trusted solaris 8 operating environment , security - enhanced linux and rfsos
最后，我们比较了基于角色的访问控制模型在三个安全操作系统中实现的特性。这三个安全操作系统是： trustedsolaris8操作环境、 selinux和红旗安全操作系统。 |
| 7. | Our finding is that these products provide a sound basis for implementing the basic features of rbac , although there are significant differences . in particular , rfsos is the only one to directly support the definitations of rbac model
通过分析和比较，我们可以看到红旗安全操作系统中的基于角色的访问控制模块比较完整地实现了基于角色的访问控制模型的定义和结构。 |
| 8. | Then , this thesis puts forward a kind of new rbac model - - ex _ rbac ; it is a kind of improvement of rbac96 model . it organizes insides resource of the information system into a kind of structure in order through introducing the concept of objectgroup , overcomes the shortcomings of rbac96 model difficult to implement in practical application
然后提出了一种扩展的基于角色的访问控制模型ex _ rbac ，它是对传统基于角色访问控制模型rbac96的一种改进，该模型通过引入对象组的概念，将信息系统的内部资源组织成一种有序结构，方便授权管理，克服了rbac96模型难于在实际应用中实现的缺点。 |
