Abstract

The development of numerous new Internet of Things (IoT) applications have been made possible by low-power, long range wide-area technology (LoRaWAN), which provides energy and cost-efficient wireless connectivity for large deployments of autonomous sensors. The security of LoRaWAN operating in the license-free frequency band, has received somewhat limited attention and numerous investigations have identified security flaws that makes it susceptible to network attacks such as Replay, Man in the Middle (MiTM) and bit-flipping attack. Current research has identified that LoRaWAN in its present form lacks synchronization between communicating parties, has a vulnerable key management and encryption process. The research has proposed an improvement in the form of dual encryption and time stamp-based synchronization check, which tends to negate these network attacks. This approach neither tampers with the core of the LoRaWAN nor the recommendations of the LoRa Alliance. The approach will lead to enhanced attack detection and mitigation capability of the protocol and make it robust for critical nodes and applications.
