Verified trustworthy software systems

Verified trustworthy software systems.

Modern society is faced with a fundamental problem: the reliability of complex, evolving software systems on which society critically depends cannot be guaranteed by the established, non-mathematical computer engineering techniques such as informal prose specification and ad hoc testing. The situation is worsening: modern companies are moving fast, leaving little time for code analysis and test...

Totally Verified Systems: Linking Verified Software to Verified Hardware

Trustworthy Tools for Trustworthy Programs: A Verified Verification Condition Generator

Verification Condition Generator (VCG) tools have been effective in simplifying the task of proving programs correct. However, in the past these VCG tools have in general not themselves been mechanically proven, so any proof using and depending on these VCGs might have contained errors. In our work, we define and rigorously prove correct a VCG tool within the HOL theorem proving system, for a s...

A Foundation for Verified Software Development Systems

We describe a formalization of the meta-mathematics of programming in a higher-order calculus as a means to create verifiably correct implementations of program synthesis tools. Formal definitions and lemmata are used to raise the level of abstraction in formal reasoning to one comprehensible for programmers. Formal metatheorems make explicit the semantic knowledge contained in program derivati...
