Risk analysis and countermeasure for bit-flipping attack in LoRaWAN

Abstract

LoRaWAN is a wireless technology optimized for low data rate and wide transmission range in IoT. Several studies have reported a security vulnerability in the LoRaWAN that could develop into an attack: bit-flipping attack. The bit-flipping attack is an attack which can change specific fields on ciphertext without decryption. In this paper, we analyze the risk of the bit-flipping attack which might occur in LoRaWAN and propose a countermeasure to prevent it.
