A Syntactic Approach to Foundational Proof-Carrying Code

Proof-carrying code (PCC) is a software mechanism that allows a host system to verify properties about an application via a formal proof that accompanies the application's executable code. The host system can quickly verify the validity of the proof, and it can compare the conclusions of the proof to its own … See more The original publication on proof-carrying code in 1996 used packet filters as an example: a user-mode application hands a function written in machine code to the kernel that determines whether or not an application is … See more • Typed assembly language • Program derivation • Formal verification • Berkeley Packet Filter See more WebNov 8, 2006 · Proof-carrying code (PCC) is a technique for downloading mobile code on a host machine while ensuring that the code adheres to the host's safety policy.

WebSep 1, 2001 · In contrast, the proofs of foundational PCC explicitly define all required types and explicitly prove all the required properties of those types assuming only a fixed foundation of mathematics such as higher-order logic. WebIn this paper, we focus on security mechanisms that are based on Proof-Carrying Code (PCC) techniques. In a PCC system, a code producer sends a code along with its safety proof to the consumer.

Proof carrying code

WebThe essence of proof-carrying code is to shift the burden of verification from the consumer to the producer, leaving the consumer with simply checking the delivered proof against the code, a task of insignificant size compared to the actual computation of the proof. Weba proof of the VC and presents that to the code consumer, who can now simply run a proof checker to satisfy itself that the VC is provable. Fig.1. The structure of a proof-carrying code system showing a “dialogue” between the code producer (on the left) and the code consumer (composed of the trusted elements shown shaded).

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.
