ID-Based Secure Distance Bounding and Localization

Free registration required

Executive Summary

In this paper, the authors propose a novel ID-based secure distance bounding protocol. Unlike traditional secure distance measurement protocols, the protocol is based on standard insecure distance measurement as elemental building block, and enables the implementation of secure distance bounding using Commercial Off-The-Shelf (COTS) ranging devices. They use the proposed protocol to implement secure Radio Frequency (RF) Time-of-Arrival (ToA) distance measurements on an UltraWideBand (UWB) ranging platform. Based on this, they implement Verifiable Multilateration - a secure localization scheme that enables the computation of a correct device location in the presence of an adversary. To the best of their knowledge, this is the first implementation of an RF ToA secure localization system.
