Abstract

Criptography is critical to the security of wireless networks. In the context of LoRa for the Internet of Things, the symmetric key distribution is a challenge. As an alternative, it is possible to generate keys in a distributed manner, based on characteristics of the physical medium, such as the RSSI indicator. This work advances the study of this approach in the context of the RSSignal framework for LoRaWAN networks. The results suggest that, even in scenarios without mobility, the RSSI variance is sufficient for the key generation process. This work also presents the LoRa RSSI Grabber for collecting and storing the RSSI indicator, besides making a new dataset with real measurements publicly available to the community.
