Security by mobility in location and track verification

Abstract

This poster presents the idea of exploiting mobility to improve the security in location and track verification. Unlike traditional approaches which require tight time synchronization or two-way communication, mobility can be used to derive lightweight verification schemes. By ensuring independent movement of the verifiers, our scheme can provide security guarantees even if the verifiers' positions are known to the attacker. We also give an outlook on more general opportunities for mobility-aided security.
