We propose to unify the treatment of a broad range of modalities in typed lambda calculi. We
do so by defining a generic structure of modalities, and show that this structure arises …

We present an expressive information-flow control type system with recursive types,
existential types, label polymorphism, and impredicative type polymorphism for a higher …

Dependency analysis is vital to several applications in computer science. It lies at the
essence of secure information flow analysis, binding-time analysis, etc. Various calculi have …

Noninterference is the strong information-security property that a program does not leak
secrets through publicly-visible behavior. In the presence of effects such as nontermination …

Differential privacy enables general statistical analysis of data with formal guarantees of
privacy protection at the individual level. Tools that assist data analysts with utilizing …

Type systems designed for information-flow control commonly use a program-counter label
to track the sensitivity of the context and rule out data leakage arising from effectful …

Rigorous reasoning about implementations of software systems requires a detailed
mathematical model of the behavior of the programming language. However, real-world …

This tutorial provides a complete and homogeneous account of the latest advances in fine-
and coarse-grained dynamic information-flow control (IFC) security. Since the 70s, the …

We show that noninterference and transparency, the key soundness theorems for dynamic
IFC libraries, can be obtained “for free”, as direct consequences of the more general …

Abstract Language-based information flow control (IFC) promises to provide programming
languages and tools that make it easy for developers to write secure code. Traditionally …
