Location-Based Pseudonyms for Identity Reinforcement in Wireless ad hoc Networks

Abstract : In this paper we introduce methods that strengthen the identity of end-devices in order to prevent impersonation attacks in wireless ad hoc networks. Pseudonyms are locally generated from Received Signal Strength Indicators (RSSI) for narrow band IEEE 802.15.4 standard or Round Trip - Time of Flight (RT-ToF) measurements (optionally, along with relative clock drift estimates) for Impulse Radio - Ultra Wideband (IR-UWB) technology. These radiolocation metrics are converted into range measurements, quantized and then fed into hash functions to produce pseudonyms. For the two benchmarked radio technologies, practical trade-offs are illustrated depending on the input measurement accuracy under different channel assumptions. The evaluated solution enables to securely guess the pseudonyms of trusted neighbors with no information leakage. It also achieves advantageous low probability of successful attacks based on brute-force or statistics-aided strategies or compared to other impersonation detection strategies (e.g. RSSI history monitoring)
