摘要
随着物联网、5G和边缘计算等技术的快速发展,时态地理信息系统(temporal geographical information system,TGIS)面临复杂多变的安全环境和访问控制需求。针对时序地理授权机制僵化、缺乏动态适应性等问题,提出了基于时序角色的TGIS访问控制模型。该模型对基于角色访问控制模型的用户、对象、角色、权限进行了扩展,增加了时序约束和空间属性,实现了对用户访问行为的精细化管控,支持基于角色、时间与位置的多维度分层次动态授权,访问控制机制更灵活有效。模型降低了TGIS系统用户权限维护的复杂度,在实际应用中取得了较好的效益。
With the rapid development of technologies such as the Internet of Things,5G,and edge computing,the temporal geographic information system(TGIS)faces a complex and ever-changing security environment and access control requirements.To address the rigidity and lack of dynamic adaptability of the temporal geographic authorization mechanism,a TGIS access control model based on temporal roles was proposed.This model extended the user,object,role,and permission of the role-based access control model,adding temporal constraints and spatial attributes,achieving refined control over user access behavior and supporting multi—dimensional and hierarchical dynamic authorization based on role,time,and location.The access control mechanism was more flexible and effective.The model reduced the complexity of user permission maintenance in the TGIS system and had achieved good benefits in practical applications.
