We developed an importer from both HOL 4 and HOL-light into Isabelle/HOL. The importer works by replaying proofs within Isabelle/HOL that have been recorded in HOL 4 or HOL-light a...
Information flow type systems provide an elegant means to enforce confidentiality of programs. Using the proof assistant Isabelle/HOL, we have machine-checked a recent work of B...
Abstract. A verified compiler is an integral part of every security infrastructure. Previous work has come up with formal semantics for sequential and concurrent variants of Java a...
General purpose theorem provers provide sophisticated proof methods, but lack some of the advanced structuring mechanisms found in specification languages. This paper builds on pr...
