中文摘要: 传统的访问控制模型采用手动的授权方式, 应用在目前混合型组织企业中, 造成权限授权复杂、准确度低. 因此, 提出一种基于用户-角色-任务的多约束访问控制模型(C-URTBAC), 该模型采用用户分级管理、权限在主体和客体间的传播性思想, 实现了半自动化的授权方式, 提高授权效率和准确度; 同时细化了约束分类, 实现了细粒度化的权限管理. 最后将该模型引用到某汽车零部件公司的PLM系统中, 验证了该模型的实用性.
Abstract:The manual way of the traditional access control model caused complex access authorization and low accuracy in the hybrid organization enterprise. And the model of C-URTBAC was put forward. The model adopted the idea of the level-to-level management of users and transmission of permissions in the subject and object. It could realize semi-automatic way of authorization, so as to improve the efficiency and accuracy of authorization. And it refined the constraint classification, realizing fine-grained permissions management. Finally the model was introduced in the PLM system of some auto parts company, verifying the practicability of the model.
