带空间特性的访问控制在汽车终端上的应用

摘要

Its major research is the use of role-based access control with spatial character in automobile terminal. Introduce the relate definitions about the location-based access control and give some restraints which can be used on the automobile terminal,hoping that can be used in the real life. The playing role of each car will change for one database when the automobile went to another place. Hope that the location-based service can provide the requisite data to the user who is authorized by the local database. In order to protect users' privacy and prevent the illegal use of private data,referred the spatial role-based access control model, described its application in automobile terminal on the restraints in spatial environment,the grant of roles, the solution of constraint violates, etc.%文中主要研究具有位置特性的访问控制技术在未来汽车智能终端上的使用.介绍了基于位置的访问控制的相关定义以及运用到汽车智能终端上的一些约束,并定义了一些相关的角色,以期能将此运用在现实生活中.汽车行驶到不同的位置,其对于某个数据库扮演的角色也会相应发生改变.基于位置的服务作为IT信息服务的重要内容,它根据汽车所处空间位置向其提供在当前环境下所需的数据信息.为了保护隐私,保证数据资源不被非法利用,参考SRBAC访问控制模型,从空间环境下的约束、角色授予、约束违反的解决方式等方面,来描述它将来在汽车终端上的应用.
