Specifying Message Formats with Contiguity Types

Authors: Konrad Slind

Published in: LIPIcs, Volume 193, 12th International Conference on Interactive Theorem Proving (ITP 2021)

Abstract

We introduce Contiguity Types, a formalism for network message formats, aimed especially at self-describing formats. Contiguity types provide an intermediate layer between programming language data structures and messages, offering a helpful setting from which to automatically generate decoders, filters, and message generators. The syntax and semantics of contiguity types are defined and used to prove the correctness of a matching algorithm which has the flavour of a parser generator. The matcher has been used to enforce semantic well-formedness conditions on complex message formats for an autonomous unmanned avionics system.

Qualification of Formal Methods Tools (Dagstuhl Seminar 15182)

Authors: Darren Cofer, Gerwin Klein, Konrad Slind, and Virginie Wiels

Published in: Dagstuhl Reports, Volume 5, Issue 4 (2015)

Abstract

Formal methods tools have been shown to be effective at finding defects in and verifying the correctness of safety-critical systems, many of which require some form of certification. However, there are still many issues that must be addressed before formal verification tools can be used as part of the certification of safety-critical systems. For example, most developers of avionics systems are unfamiliar with which formal methods tools are most appropriate for different problem domains. Different levels of expertise are necessary to use these tools effectively and correctly. In most certification processes, a tool used to meet process objectives must be qualified. The qualification of formal verification tools will likely pose unique challenges.
