Survey of Distance Bounding Protocols and Threats

International audienceNFC and RFID are technologies that are more and more present in our life. These technologies allow a tag to communicate without contact with a reader. In wireless communication an intruder can always listen and forward a signal, so he can mount a so-called worm hole attack. In the last decades, several Distance Bounding (DB) protocols have been introduced to avoid such attacks. In this context, there exist several threat models: Terrorist Fraud, Mafia Fraud, Distance Fraud etc. We first show the links between the existing threat models. Then we list more than forty DB protocols and give the bounds of the best known attacks for different threat models. In some cases, we explain how we are able to improve existing attacks. Then, we present some advices to the designers of the DB protocols and to the intruders to mount some attacks

Distance bounding under different assumptions

Distance-bounding protocols were introduced in 1993 as a countermeasure to relay attacks, in which an adversary fraudulently forwards the communication between a verifier and a distant prover. In the more than 40 different protocols that followed, assumptions were taken on the structure of distance-bounding protocols and their threat models. In this paper, we survey works disrupting these assumptions, and discuss the remaining challenges
