论文摘要
为了提高现有模型的明确性能，本文提出了基于良好的出处的访问控制策略模型。该方法采用出处作为条件来确定是否可以访问一块数据，因为在数据上执行的历史操作可以揭示其敏感性和脆弱性的线索。特别是，我们提议的工作提供了一个四评估的决策集，允许显示状态特别匹配限制。该框架由目标策略，访问控制策略和政策代数组成。通过完整的定义和代数系统构建，开发了实用的细粒访问控制策略模型。
A fine-grained provenance-based access control policy model is proposed in this paper, in order to improve the express performance of existing model. This method employs provenance as conditions to determine whether a piece of data can be accessed because historical operations performed on data could reveal clues about its sensitivity and vulnerability. Particularly, our proposed work provides a four-valued decision set which allows showing status to match a restriction particularly. This framework consists of target policy, access control policy, and policy algebras. With the complete definition and algebra system construction, a practical fine-grained access control policy model is developed.
