Proof-Producing Program Analysis

چکیده

Proof-producing program analysis augments the invariants inferred by an abstract interpreter with their correctness proofs. If these invariants are precise enough to guarantee safety, this method is an automatic verification tool. We present proof-synthesis algorithms for a simple flow chart language and domains V → V mapping variables to abstract values and discuss some benefits for proof carrying code systems. Our work has been carried out in Isabelle/HOL and incorporated within a verified proof carrying code system.

Validated Proof-Producing Decision Procedures

A widely used technique to integrate decision procedures (DPs) with other systems is to have the DPs emit proofs of the formulas they report valid. One problem that arises is debugging the proof-producing code; it is very easy in standard programming languages to write code which produces an incorrect proof. This paper demonstrates how proof-producing DPs may be implemented in a programming lan...

The ASTREÉ Analyzer

ASTRÉE is an abstract interpretation-based static program analyzer aiming at proving automatically the absence of run time errors in programs written in the C programming language. It has been applied with success to large embedded control-command safety critical realtime software generated automatically from synchronous specifications, producing a correctness proof for complex software without...

A Proof-Producing Software Compiler for a Subset of Higher Order Logic

We discuss a proof-producing compiler which translates first order recursion equations, defined in higher order logic, to assembly language. The front end of the compiler is based on a series of source-tosource translations, starting with a semantic CPS translation and culminating in graph-colouring register allocation. Equality of the original program and the result of register allocation is p...

Instrumentation Analysis: An Automated Method for Producing Numeric Abstractions of Heap-Manipulating Programs

A number of questions regarding programs involving heap-based data structures can be phrased as questions about numeric properties of those structures. A data structure traversal might terminate if the length of some path is eventually zero or a function to remove n elements from a collection may only be safe if the collection has size at least n. In this thesis, we develop proof methods for re...

Ghost Map: Proving Software Correctness using Games

A large amount of intellectual effort is expended every day in the play of on-line games. It would be extremely valuable if one could create a system to harness this intellectual effort for practical purposes. In this paper, we discuss a new crowd-sourced, on-line game, called Ghost Map that presents players with arcade-style puzzles to solve. The puzzles in Ghost Map are generated from a forma...
