The underlying type theory is a\u00a0\u03bb-calculus equipped with refinement types for expressing pre- and post-conditions within first-order logic. We derive formal cryptographic primitives and represent active adversaries within the type theory. Well-typed programs enjoy assertion-based security properties, with respect to a realistic threat model including key compromise. The implementation amounts to an enhanced typechecker for the general purpose functional language F#; typechecking generates verification conditions that are passed to an SMT solver. We describe a series of checked examples. This is the first tool to verify authentication properties of cryptographic protocols by typechecking their source code.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We present the design and implementation of a typechecker for verifying security properties of the source code of cryptographic protocols and access control mechanisms.

F7 pioneers the static checking of security properties expressed with refinement types. Although the original motivation was to check security properties, F7 is not security-specific and is applied in other areas, such as database modelling. The theoretical core of F7 is the typed lambda-calculus Refined Concurrent FPC, or RCF for short.
