Attacks on Karlsson and Mitrokotsa's Grouping-Proof-Distance-Bounding Protocol
Roel Peeters, Jens Hermans and Aysajan Abidin
Abstract
In the recent IEEE communication letter ``Grouping-Proof-Distance-Bounding Protocols: Keep All Your Friends Close" by Karlsson and Mitrokotsa, a protocol for grouping-proof distance-bounding (GPDB) is proposed. In this letter, we show that the proof that is generated by the proposed GBDP protocol does not actually prove anything. Furthermore, we provide a construction towards a distance-bounding grouping-proof, however it remains unclear if one can ever truly combine (privacy-preserving) distance-bounding and a grouping-proof.
