WSN Authentication using RF Fingerprints (D.
Knox and T. Kunz)
RF Fingerprint Credential - Usage
§Objective:
Generate a credential using the aggregated RF Fingerprint information
for a given subject node
§Credential
is generated by a specific set of nodes in a particular neighbourhood
–Identification
information for those nodes is included in the credential
§Resulting
Credential can be ‘shown’ by the subject node outside the neighbourhood
within which it was generated
§RF
Fingerprints of the referees are also included in the Credential
–RF Fingerprints of
the referees can only be verified by other neighbours, but not required
to be in the same neighbourhood as the one used for credential
generation.
–A reputation or
trust system is required to monitor the behaviour of nodes, but this system
requires the identifying information from the credentials.
§The
method for showing the credential is not discussed in the paper.
