Abstract
A notion of open bisimulation is proposed for the Applied Pi Calculus, which extends π-calculus in
order to facilitate analyzing security protocols. Our notion is based on the labeled transition system,
and takes a knowledge aware open approach to model knowledge in security protocols. It is shown
to be sound to labeled bisimilarity and is a congruent relation. As a running example, we analyze
two e-commerce protocol, namely iKP and Ferguson’s electronic cash protocol, by Applied Pi and
open bisimilarity.
