Abstract:
Access Control is an important technology in system security, but it is new for collaborative design. This paper provides a new framework of multi-level access control based on hierarchical product modeling. A layered privilege model is developed to provide multi-granularity access permissions in the part level and feature level. It implements Role-Based Extended Hierarchy Access Control(RBEHAC) model, which is integrated with layered privilege model and common RBAC.
Key words:

摘要: 访问控制是系统安全的重要技术,但在协同设计中应用较少。该文提出一个基于零件层次建模的多层访问控制框架用于协同设计,其中的层次权限模型为3D图形设计提供了部件层和特征层的多级访问许可,通过结合层次权限概念和传统的角色访问控制,实现基于角色的扩展层次访问控制模型。
