Zusammenfassung
In this research, we propose leveraging Physical
Layer Security (PLS) for Secret Key Generation (SKG) to
enable secure session key management within Long Range
Wide Area Network (LoRaWAN). We further introduce the
use of autoencoders for Reciprocity Enhancement (RE) to
enhance the SKG performance in terms of Bit Disagreement
Rate (BDR) and Key Generation Rate (KGR).
To evaluate the eff ectiveness of our proposed approach, we con-
ducted experiments using an experimental LoRaWAN testbed.
We present the obtained results, which highlight the promising
potential of PLS based key management in terms of improved
BDR and KGR using Received Signal Strength Indicator
(RSSI) measurements. The fi ndings further demonstrate the
feasibility and benefi ts of integrating autoencoders into the
PLS based key management process in LoRaWANs.
