LoRaWAN network security using simulated scenarios

Abstract

The article describes the LoRaWAN network. LoRaWAN is a communication protocol that provides long-distance communication with low power consumption. Long Range Wide Area Networks (LoRaWAN) is open-center access (MAC) layer technology designed for long-distance connections with a large number of low-energy devices. LoRaWAN devices in various network settings use the most modern network simulator (NS-3). First, one device and its mobility are introduced. Due to its properties, the protocol is very popular in the field of the Internet of Things. In this context, the security of this protocol is of great importance given the current ubiquity of the Internet. The article deals with eavesdropping and eavesdropping combined with decryption of LoRaWAN communication on the physical layer and on the Media Access Control sublayer of the line layer. The article focuses on the security gap within the backward compatibility of the LoRaWAN protocol. It currently uses the LoRaWAN protocol in version 1.1.x, which addresses the main security gap from the previous 1.0.x protocol. The article uses a software-defined radio to listen to the news. The article verify backward compatibility by replaying the message and sending the fake message to the server. © 2021 International Multidisciplinary Scientific Geoconference. All rights reserved.
