This paper presents a new approach for ensuring that security-critical software correctly enforces its information release policy. Our approach has two parts. First, an information release policy is specified as a security automaton written in a new language called AIR. Second, we enforce an AIR policy by translating it into an API for programs written in λAIR, a core formalism for a functional programming language. λAIR uses a novel combination of dependent, affine, and singleton types to ensure that the API is used correctly. As a consequence we can certify that programs written in λAIR meet the requirements of the original AIR policy specification. %B Proceedings of the 2008 Workshop on Programming Languages and Analysis for Security.
