Distance bounding protocols have been previously
introduced to establish upper and lower bounds on the distance
between two entities. This article demonstrates how coupled
transmission techniques, stemming from the domain of wireless
power transfer, can be used for distance bounding. The proposed
approach can detect and prevent distance enlargement frauds,
which were deemed unsolvable for electromagnetic propagation based distance bounding protocols. The effectiveness of the
proposed approach is demonstrated and evaluated via numerical
simulations. The results suggest that the proposed approach is
capable of measuring the distance between two devices communicating via inductive coupling with an average accuracy of
8:14 cm when using a hardware with 12-bit voltage measurement
resolution in the absence of noise.
