Abstract
We present an improved logic for analysing authentication
properties of cryptographic protocols, based on the SVO logic of
Syverson and van Oorschot (1994). Such logics are useful in electronic
commerce, among other areas. We have constructed this logic in order to
simplify automation, and we describe an implementation using the
Isabelle theorem-proving system, and a GUI tool based on this
implementation. The tool is typically operated by opening a list of
propositions intended to be true, and clicking one button. Since the
rules form a clean framework, the logic is easily extensible. We also
present in detail a proof of soundness, using Kripke possible-worlds
semantics
