Password Authenticated Key Agreement for Contactless Smart Cards

This paper describes and compares the usage of password- based authenticated key agreement protocols to establish a secure com- munication channel between terminal and contactless card. In particu- lar, protocols of this kind are discussed for use in contactless ID cards. The aim of this paper is to discuss, for the first time, two cryptographic password-based protocols with respect to security, implementation eorts and performance. Furthermore, a real life implementation on NXP's high security SmartMX chip is presented.
