Distance Bounding: A Practical Security
Solution for Real-Time Location Systems
The need for implementing adequate security services in
industrial applications is increasing. Verifying the physical
proximity or location of a device has become an important
security service in ad-hoc wireless environments. Distance-
bounding is a prominent secure neighbor detection method that
cryptographically determines an upper bound for the physical
distance between two communicating parties based on the
round-trip time of cryptographic challenge-response pairs. This
paper gives a brief overview of distance-bounding protocols and
discusses the possibility of implementing such protocols within
industrial RFID and real-time location applications, which
requires an emphasis on aspects such as reliability and real-time
communication. The practical resource requirements and
performance tradeoffs involved are illustrated using a sample of
distance-bounding proposals, and some remaining research
challenges with regards to practical implementation are
discussed.
