So Near and Yet So Far – Symbolic Verification of Distance-Bounding Protocols

The continuous adoption of Near Field Communication (NFC) tags offers many new applications whose security is essential (e.g., contactless payments). In order to prevent flaws and attacks, we develop in this article a framework allowing us analyse the underlying protocols, taking into account location agents transmission delay when exchanging messages. We propose two reduction results render automatic verification possible relying on existing tool ProVerif . Our first result allows one consider unique topology catch all attacks. second simplifies analysis considering Terrorist fraud. Then, based these results, perform comprehensive case study (27 protocols), which obtain proofs for some protocols detect attacks others.
