Abstract
Currently there are multiple ways of verifying the identity and integrity of Internet of Things (IoT) sensors based on, for example, the Trusted Computing Group’s (TCG’s) Guidance for Securing Network Equipment, software-centered approaches such as using a checksum, and using an in-band and out-of-band approaches for integrity validation. In each of these approaches, trustworthiness may be based on limited artifacts. As well, none of these approaches employ quantum resistant secure key exchange methods between a Long Range (LoRa) Wide Area Network (LoRa) (LoRaWAN) Gateway and sensors. To address these challenges techniques are presented herein that apply an attestation method to the Constrained Application Protocol (CoAP), which is used between a LoRa Gateway and sensors, to provide "proof of integrity" and "freshness of proof of integrity" (in other words, trustworthiness) to IoT sensor devices. An Attestation ID that is derived through an attestation method is shared in data traffic (i.e., in-band) securely using a Post-Quantum Cryptography (PQC) method.
