中文摘要: |
由于在目前的各种组织授权模型中缺乏对授权系统访问许可的检验,提出了对OB4LAC模型授权情况进行验证的基于组织的访问控制系统授权验证单层关系模型,通过向量和矩阵对用户-岗位-角色-操作之间的关联方式进行了描述,实现在多用户情况下,将每个用户通过组织授权系统所得到的系统操作权限进行直观的统计.通过算法实例对单层关系模型进行了实际验证,验证结果清晰直观地反映了组织内部人员的系统权限分配情况,对系统安全访问控制提供了有力支持. |
英文摘要: |
The situation of the authorized system accessing permissions by the organization authorization model was seldom verified. A single-layer access control authorized verification model based on organization for OB4LAC model was put forward, and the relationships between user, position, role and operation were also described by the vectors and matrices. The system operation permission of each user got from organization system were counted directly when multi-user existing in one system. An example to verify the single-layer access control verification model is given and the results clearly show the situation of all the users to allocate authorization. This model is helpful to system security and access control. |
