WSN Authentication using RF Fingerprints (D. Knox and T. Kunz)
Related Work – WSN Authentication and RF Fingerprints
§Key establishment in wireless networks
–Mostly based on key pre-distribution
–Other methods measure feasibility of time or space properties of node signals
§Use of physical attributes for authentication in wireless networks
–physical proofs of presence from nodes (e.g. based on physical contact or based on other auxiliary channels that are fully trusted)
§Impossibility results for distributed consensus
–A ‘majority’ of honest nodes is required to reach consensus (or even stronger requirements)
–Distributed credentials are also affected by this result
§RF fingerprints
–Recently advocated for WSNs
–Not measured as being perfectly consistent or reliable (no study of resiliency to attack)
§Burmester/Desmedt present a method for shared conference key establishment
