WebProof-Carrying Code (PCC) is a general framework for verifying the safety properties of machine-language programs. PCC proofs are usually written in a logic extended with language-speci c typing rules; they certify safety but only if there is no bug in the typing rules. WebJan 16, 2007 · In this paper we present an open framework for foundational proof-carrying code (FPCC). It allows program modules to be specified and certified separately using different type systems or program logics. Certified modules (i.e., code and proof) can be linked together to build fully certified systems.
