Extensions to an Authentication Technique Proposed for the Global Mobility Network

We present three attacks against the authentication protocol that has been proposed for the so called global mobility network in \cite{kn:Suz97}. We show that the attacks are feasible and propose corrections that make the protocol more robust and resistant against the presented attacks. Our aim is to highlight some basic design principles for cryptographic protocols, the adherence to which would have prevented these attacks.
