POSTER: Secure Path Verification using Mobility-Differentiated ToA

In this poster, we generalize the problem of secure location verification to that of path verification and propose a scheme to securely verify the claims of a mobile node that moves along a path. Although the secure verification of location claims has been studied extensively in the literature, current solutions require very strict time synchronization of the verifiers, or extra communication and special-purpose hardware. However, we propose a lightweight verification scheme exploiting the mobility of the claimer in path verification without need for time synchronization and communication overhead.
