| Abstract |
Distance-Based Message Authentication provides an additional layer of access control and helps to defend against key compromise and denial-of-service attacks on constrained nodes. The range between sender and receiver is measured securely. Messages sent from outside a defined physical radius can be rejected early, protecting vulnerable higher layers. We show our initial implementation of a modified protocol using the Nanotron NA5TR1. We show how changing MAC addresses can avoid modification to ranging hardware. |
