Password Based Key Exchange With Hidden Elliptic Curve Public Parameters

The authors here describe a new Password-based Authenticated Key Exchange (PAKE) protocol based on elliptic curve cryptography. They prove it secure in the Bellare-Pointcheval-Rogaway (BPR) model. A significant novelty in the paper is that the proposal is conceived in 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, there will exist most probably a way to link these parameters with the nationality of the ID document owners.
