Abstract
Described is a source program code language that facilitates the association of security proofs obtained from a solver (e.g., a Z3 theorem prover) with the program code. The code may include affine types, dependent types and/or refinement types. A derefinement procedure replaces each refinement type with a dependent pair type corresponding to the proof. A target code type checker verifies the target code with respect to the security policies. If verified as complying with security policy, a verified program corresponding to the translated program may then be installed and run.
