Title:
Password Based Key Exchange with Hidden Elliptic Curve Public Parameters

Authors: Julien Bringer, Herve Chabanne, Thomas Icart

Abstract:

We here describe a new Password-based Authenticated Key Exchange (PAKE) protocol based on elliptic curve cryptography. We prove it secure in the Bellare-Pointcheval-Rogaway (BPR) model. Our proposal is conceived in a such a way that it ensures that the elliptic curve public parameters remain private. This is important in the context of ID contactless devices as, in this case, it is easy to link these parameters with the nationality of the ID document owners.
