We use the interactive theorem prover Isabelle to prove that the algebraic axiomatization of bisimulation equivalence in the pi-calculus is sound and complete. This is the first ...
Abstract—In any formal theory, a proof is a sequence of well formed formulas (wff). Here, we consider the digraph whose nodes are proofs and the edges are pairs of proofs such t...
This paper gives the first proof that the subtyping relation of a higherorder lambda calculus, Fω ≤, is anti-symmetric, establishing in the process that the subtyping relation...
We give the first proof of security for the full Unix password hashing algorithm (rather than of a simplified variant). Our results show that it is very good at extracting almost...
