Mathieu Baudet, Véronique Cortier, and Stéphanie Delaune. YAPA: A generic tool for computing intruder knowledge. In Proceedings of the 20th International Conference on Rewriting Techniques and Applications (RTA'09), pp. 148–163, Lecture Notes in Computer Science 5595, Springer, Brasília, Brazil, June 2009.
Reasoning about the knowledge of an attacker is a necessary step in many formal analyses of security protocols. In the framework of the applied pi calculus, as in similar languages based on equational logics, knowledge is typically expressed by two relations: deducibility and static equivalence. Several decision procedures have been proposed for these relations under a variety of equational theories. However, each theory has its particular algorithm, and none has been implemented so far.
We provide a generic procedure for deducibility and static equivalence that takes as input any convergent rewrite system. We show that our algorithm covers all the existing decision procedures for convergent theories. We also provide an efficient implementation, and compare it briefly with the more general tool ProVerif.
