On the automated synthesis of proof-carrying temporal reference monitors

Abstract

We extend the range of security policies that can be guaranteed with proof carrying code from the classical type safety, control safety, memory safety, and space/time guarantees to more general security policies, such as general resource and access control. We do so by means of (1) a specification logic for security policies, which is the pasttime fragment of LTL, and (2) a synthesis algorithm generating reference monitor code and accompanying proof objects from formulae of the specification logic. To evaluate the feasibility of our approach, we developed a prototype implementation producing proofs in Isabelle/HOL. © Springer-Verlag Berlin Heidelberg 2007.
