PRBAC:一种基于角色的起源访问控制模型

PRBAC:A role-based provenance access control model

为了更好地利用数据起源对其它数据进行访问控制,建立了一种基于角色的起源访问控制模型(PRBAC).该模型以基于起源的访问控制模型(PBAC)和基于角色的访问控制模型(RBAC)为基础,划分了作为访问控制基础的依赖关系列表,并引入RBAC中角色集的概念,给出了具体的访问控制算法.分析结果表明PRBAC能解决基于起源的访问控制模型中授权管理不灵活、系统运行效率低和访问控制策略不够安全等问题.

T his paper proposes a novel role-based provenance access control model (PRBAC )to better utilize provenance data to control access to the other data .The model is built on prove‐nance-based access control (PBAC) and role-based access control (RBAC) .And this scheme di‐vided the dependency list as a foundation of access control ,introduced the notion of role in role-based access control and gave out the access control algorithm .The analysis results indicate the proposed model can solve the issues that the authorization management is not flexible ,the system has low access efficiency and access control policy is not secure enough ,and other problems .
