Idea – Binding Physical Layer to Data Layer
§ RF Fingerprints are physical layer entities
Measurements are made by neighbours (that are within RF range)
Real WSN hardware is simplex (nodes cannot listen to themselves)
§ Need a way to link RF Fingerprints with higher protocol layers to
allow authentication to take place at a network level
§ Our proposal:
1. Neighbour Discovery using RF Fingerprints
2. Creation of a ‘neighbourhood’ Conference Key
3. RF Fingerprint Exchange (within the ‘neighbourhood’)
4. RF Fingerprint secure aggregation (within the ‘neighbourhood’)
5. RF Fingerprint-based credential creation and usage (which can be used outside
the ‘neighbourhood’, but use the maximal set of neighbours as referees)
