摘要:

Contactless communications have become omnipresent in our daily lives, from simple access cards to payment devices. Such systems are particularly vulnerable to relay attacks, in which an attacker relays the messages from a distant prover (the card) to a verifier (the terminal). By using this technique, he can impersonnate the prover to the verifier. Distance-bounding protocols were introduced to counter such attacks. The idea is to add a time measurement for the messages in order to verify the proximity of the prover.

In this talk I will present the core ideas of distance bounding protocols and the associated security challenges.
