How Distance-Bounding Can Detect Internet Traffic Hijacking.

We propose a two-party cryptographic protocol for detecting traffic hijacking over the Internet. Our proposal relies on a distance-bounding mechanism that measures the round-trip time of packets to decide whether an attack is ongoing. The protocol requires only two cryptographic operations per execution which leads to very few additional workload for the users. We demonstrate the efficiency of the protocol using large-scale experiments and we discuss the choice of the decision function w.r.t. the false positive and negative cases.
