Secure Information Flow in a Multi-Threaded Imperative Language
Previously, we developed a type system to ensure secure information flow in a sequential, imperative programming language [VSI96]. Program variables are classified as either hig...

Probabilistic Noninterference in a Concurrent Language
In previous work [16], we give a type system that guarantees that well-typed multithreaded programs are possibilistically noninterfering. If thread scheduling is probabilistic, ho...

Probabilistic Noninterference through Weak Probabilistic Bisimulation
To be practical, systems for ensuring secure information flow must be as permissive as possible. To this end, the author recently proposed a type system for multi-threaded progra...

Secure information flow with random assignment and encryption
Type systems for secure information flow aim to prevent a program from leaking information from variables classified as H to variables classified as L. In this work we extend such...
