Thirdly , this paper presents a new model called multi - database , workflow and role - based access control ( mdwrbac ) , on the basis of full analyzing role - based access control models . the characters of mdwrbac model are as follows 对安全访问控制模型进行研究,提出了一种适应公文流转系统的基于多数据库、工作流与角色的访问控制( mdwrbac )模型。
Research on gfac and flask , presents an access control model frame suitable for ertos , this frame has open architecture and is easy to extend . 5 . deeply studies windows ce codes , realizes mpacm in windows ce to enhance its security 该模型充分考虑了嵌入式系统应用的多样性,综合了几种访问控制模型的优点,能对主客体的安全标记进行有效管理,重点加强主体对客体的强制访问控制。
With the in - depth analysis of the concept and theory about safely access control and rbac model , this paper puts forward a rough architecture of a safely access control model based rbac , the essential meaning and function of its component are discussed too 通过对安全访问控制技术及rbac模型深入分析,本文提出了在intranet internet环境下基于rbac模型的安全访问控制系统的总体结构,并具体分析系统的各个组成部分功能及其相互关系。
We introduce the design and implementation of the multiple policies access control model of ercist 4 . 0 secure operating system in this thesis . we can choose to use only one access control mechanism or several access control mechanisms at the same time in the secure operating system 本文对安胜4 . 0安全操作系统的多策略的访问控制模型的设计和实现进行了介绍,系统中可以单独采取某一种访问控制机制,也可以同时采取多种访问控制机制。
Secondly , it focuses on the technology of b / s mode developed on lotus domino / notes platfom . afterwards it presents a role - based access control model to sovel the problem of an normal document visited and operated safely by a different figure belong to a different department . and it presents a secure office workflow based on our designed secure access control model to make the document flow to the right figure user in network by workflow engine 接着重点研究了在lotusdomino / notes平台上实现web访问方式的技术特点,同时引入了基于角色的安全访问控制模型,解决了不同部门、不同身份的用户访问不同的文档信息和对文档的安全操作,使办公文档得以安全控制;在角色的安全访问控制模型的基础上,提出了基于角色控制的安全工作流模型,使文档在工作流引擎的驱动下,在网络环境中流向正确用户。
