Proof carrying code

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. WebProof Carrying Code (PCC) is an emerging technology whose pervasive adoption in global computers requires signi cant advances. Its founding principle (see Chapter 2), is that incoming components should come equipped with veri able evidence of their adherence to an appropriate policy that may involve requirements

WebProof-Carrying Code (PCC) is a solution to this problem wherein a code consumer can verify that code provided by an untrusted code producer adheres to a certain safety policy. The safety policy is a set of rules chosen by the code consumer. These rules define which programs will be WebProof-carrying code is a framework for the mechani-cal verification of safety properties of machine language programs, but the problem arises of quis custodiat ip-sos custodes—who will verify the verifier itself?
