Abstract

There is a rapid increase in the development of IOT applications which provides connectivity between devices but exposes them to security threats. LoRaWAN offers low power, cost-effective wireless communications across large networks. Robust authentication is essential for LoRaWAN networks as several vulnerabilities like device impersonation, replay attacks, MITM attacks can disrupt the entire system. This research develops an authentication strategy in which the data packet is appended with a time-synchronized random nonce generator, which is verified at the gateway to authenticate the devices. A proof-of-concept prototype solution was modelled in MATLAB to showcase this functionality. Upon security analysis and evaluation, factors like complexity and data processing time showed significant changes and the risk of spoofing, MITM attack, replay attack, bitflipping attack have been reduced. The approach in this research does not tamper with the standard operating procedures of the LoRa protocol. Further potential exists to incorporate anomaly detection through machine learning models, and real-world deployments for immediate accuracy.
