%T Verifying parameterized protocols by transforming stratified logic programs
%U http://eprints.imtlucca.it/1383/
%X We propose a method for the specification and the automated verification of temporal properties of parameterized protocols. Our method is based on logic programming and program transformation. We specify the properties of parameterized protocols by using an extension of stratified logic programs. This extension allows premises of  clauses to contain first order formulas over arrays of parameterized length. A property of a given protocol is proved by applying suitable unfold/fold transformations to the specifiation of that protocol.We demonstrate our  method by proving that the parameterized Peterson's protocol among N processes, for any N ≥ 2, ensures the mutual exclusion property.
