Probabilistic Localization and Tracking of Malicious Insiders Using Hyperbolic Position Bounding in Vehicular Networks

Free registration required

Executive Summary

A malicious insider in a wireless network may carry out a number of devastating attacks without fear of retribution, since the messages it broadcasts are authenticated with valid credentials such as a digital signature. In attributing an attack message to its perpetrator by localizing the signal source, the authors can make no presumptions regarding the type of radio equipment used by a malicious transmitter, including the transmitting power utilized to carry out an exploit. Hyperbolic Position Bounding (HPB) provides a mechanism to probabilistically estimate the candidate location of an attack message's originator using Received Signal Strength (RSS) reports, without assuming knowledge of the transmitting power.
