Using Distance-Bounding Protocols to Securely Verify the Proximity of Two-Hop Neighbours

Artikel i vetenskaplig tidskrift, 2015

Distance-bounding protocols allow devices to cryptographically verify the physical proximity of two parties and is a prominent secure neighbour detection method. We describe how existing distance-bounding protocols could be modified to verify the proximity of both next-hop and two-hop neighbours. This approach allows a node to verify that another node is a physical next-hop neighbour, and also detects legitimate neighbours who make dishonest claims as to who their neighbours are. This approach could prevent dishonest neighbours from hoarding traffic as the result of advertising false two-hop routes.
