Distance-bounding proof of knowledge protocols to avoid terrorist fraud attacks

Bussard, Laurent;Bagga, Walid

Research report RR-04-109

Real-time frauds can be applied against numerous zero-knowledge or minimal disclosure identification schemes that protect physical services, be it opening a door or verifying attributes of a certified device. In [4], Brands and Chaum proposed distance-bounding protocols to forbid mafia fraud attacks and let the terrorist fraud attack as an open issue. In this paper, we describe an extension of the initial scheme in order to forbid both mafia and terrorist fraud attacks.
