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 lAIR, a core formalism for a functional programming language. lAIR 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 lAIR meet the requirements of the original AIR policy specification.}, keywords = {affine types, certified evaluation, declassification, dependent types, singleton types, state modifying policies}, isbn = {0362-1340}, doi = {10.1145/1513443.1513448}, url = {http://doi.acm.org/10.1145/1513443.1513448}, author = {Swamy,Nikhil and Hicks, Michael W.} }
