Finite variant property

WebAbstract. In this tutorial, we give an overview of the Maude-NRL Protocol Analyzer (Maude-NPA), a tool for the analysis of cryptographic protocols using functions that obey different equational theories. We show the reader how to use Maude-NPA, and how it works, and also give some of the theoretical background behind the tool. WebIn this work we present an alternative method to obtain unification algorithms for combined theories based on variant narrowing. Although variant narrowing is less efficient at the ...
