R. D. Arthan
1991 Lecture Notes in Computer Science  
Acknowledgments The FST project (IED project 1563) is jointly funded by International Computers Limited and by the Information Engineering Directorate of the UK Department of Trade and Industry. [  ...  No formal proof work has been carried out on the material in this document, however proof work has begun on the HOL specification of the proof tool for HOL on which this paper has been based.  ...  A key aspect of the approach is explicit specification of a formal object modelling the kernel of the system of which one can postulate formally the desired critical properties.  ...

Formally Verifying Industry Cryptography

Mike Dodds
2022 IEEE Security and Privacy  
Acknowledgments This article is a product of many conversations with the Galois team working on industry verification.  ...  A Tool in the Toolbox We see formal verification as one tool for software assurance, alongside other methods such as testing, code audits, and fuzzing.  ...  Like other assurance tools, formal verification comes with a cost. Constructing such proofs requires a significant proof engineering effort.  ...

The industrial success of verification tools based on stålmarck's method [chapter]

Arne Borälv
1997 Lecture Notes in Computer Science  
An implementation of the method, called Prover, has been used as proof engine in various commercial tools since 1990, and is now integrated in a formal verification framework called NP-Tools.  ...  Sts Method is a patented natural deduction proof method with a novel proof-theoretic notion of proof depth, defined as the largest number of nested assumptions in the proof.  ...  Also Volvo Car Corporation have used NP-Tools for developing formal specifications.  ...

Extending formal reasoning with support for hardware diagrams [chapter]

Kathi Fisler
1995 Lecture Notes in Computer Science  
We demonstrate some advantages of formally supporting diagrams in hardware verification systems via a simple example from the verification of a single-pulser.  ...  Diagrams have been left as an informal tool in hardware reasoning, thus rendering them unacceptable representations within formal reasoning systems.  ...  of a single-pulser than the two sentential specifications.  ...

2006 Journal of Database Management  
UB2SQL is a tool for designing and developing database applications using UML and B formal method. The approach supported by UB2SQL consists of two successive phases.  ...  To overcome the lack of rules and tactics in the B prover, UB2SQL de-fines specific rules and tactics making the proof task seem like a push-button activity.  ...  Formal proofs are another theme in formal methods. The objective is to increase the degree of proof-automation.  ...

UniForM Perspectives for Formal Methods [chapter]

Bernd Krieg-Brückner
1999 Lecture Notes in Computer Science  
Trends for Formal Methods are reviewed and illustrated by several industrial applications: logical foundations of combination, verification, transformation, testing, and tool support.  ...  Instead, the solution is a variety of formalisms that complement each other, each adapted to the task at hand: specification languages and development methodologies, specific development methods or proof  ...  Standard Family of Specification Languages A standard formalism for all aspects of formal methods seems pragmatically undesirable (if not impossible) since a projection to a restricted and supposedly simpler  ...

An Overview of RoZ : A Tool for Integrating UML and Z Specifications [chapter]

Sophie Dupuy, Yves Ledru, Monique Chabre-Peccoud
2000 Lecture Notes in Computer Science  
Our approach is based on the expression of the UML class diagram and its annotations into a Z formal specification.  ...  This paper presents an approach and a tool to increase specification quality by using a combination of UML and formal languages.  ...  Thanks are also due to José-Celso Freire from UNESP (São Paulo, Brasil) for his useful suggestions on the documentation and the distribution of RoZ.  ...

Reasoning with executable specifications [chapter]

Yves Bertot, Ranan Fraer
1995 Lecture Notes in Computer Science  
This work is a case study of an environment integrating executable tool generation and formal reasoning on these tools.  ...  Starting from the specification of a small imperative programming language, and the description of two program transformations on this language, we formally prove the correctness of these transformations  ...  In the other area interested in formal specifications, the central tool is a proof tool like Coq [DFH+93], HOL [MT92], or Elf [Pfe89] rather than a programming environment.  ...
