Abstract: Physical Layer Security (PLS) uses channel parameters to generate secret keys to secure communications between legitimate users.However, implementing PLS on Long Range (LoRa) networks faces challenges such as low reciprocity, a trade-off between key disagreement and generation rates, and limited key randomness due to the many LoRa network implementations on fixed networks.This research introduced a new method for choosing optimal window lengths in Savitzky-Golay filters combined with modified SKYGlow quantizations, outperforming previous works that did not use optimal window lengths and used 4-ary quantization.Experimental results show a significant increase, with the key generation rate reaching 6.9537 bps and decreasing the key disagreement rate to 0.07827.Thus, generating a key of 128 bits takes only 18.4 s.This research significantly contributes to developing more reliable and secure SKG techniques on LoRa networks.
