Abstract

We address the issue of declassification in a language-based security approach. We introduce, in a Core ML-like language with concurrent threads, a declassification mechanism that takes the form of a local flow policy declaration. The computation in the scope of such a declaration is allowed to implement information flow according to the local policy. This dynamic view of information flow policies is supported by a concrete presentation of the security lattice, where the confidentiality levels are sets of principals, similar to access control lists. To take into account declassification, and more generally dynamic flow policies, we introduce a generalization of non-interference, that we call the non-disclosure policy, and we design a type and effect system for our language that enforces this policy.
论解密与保密政策
我们以基于语言的安全方法解决解密问题。我们在具有并发线程的核心ml类语言中引入了一种解密机制,该机制采用本地流策略声明的形式。允许该声明范围内的计算根据本地策略实现信息流。信息流策略的动态视图由安全格的具体表示支持,其中机密级别是一组主体,类似于访问控制列表。为了考虑到解密,以及更普遍的动态流策略,我们引入了一种非干扰的泛化,我们称之为非披露策略,我们为我们的语言设计了一个类型和效果系统来执行该策略。
