On the Reachability Problem in Cryptographic Protocols

Roberto M. Amadio 1, Denis Lugiez 1

N° RR-3915 (2000)

Résumé : We study the verification of secrecy and authenticity properties for cryptogra- phic protocols which rely on symmetric shared keys. The verification can be reduced to check whether a certain parallel program which models the protocol and the specification can reach an erroneous state while interacting with the environment. Assuming finite principals, we present a simple decision procedure for the reachability problem which is based on a symbolic' reduction system.
