Proof carrying code
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 WebFirearms.

WebThis entire method is referred to as proof-carrying code (PCC) because we transmit a program with its proof to a checker that then decides whether to run it or not. How the checker works depends on the language used. We will consider proofs at the level of assembly language.
