Proof-of-Location (PoL) is a lightweight security concept for Internet-of-Things (IoT) networks, focusing on the sensor nodes as the least performant and most vulnerable parts of IoT networks. PoL builds on the identification of network participants based on their physical location. It introduces a secondary message type to exchange location information. Via these messages, the nodes can verify the integrity of other network participants and reach a consensus to identify potential attackers and prevent malicious information from spreading. The paper presents the concretization of the concept to allow implementation on real hardware. The evaluation based on this implementation demonstrates the feasibility of PoL and enables identifying further steps to develop a deployable protocol.
