Counter measures against replay attacks on LoRaWAN based devices in IoT networks

Abstract

Recently, LoRaWAN became one of the most important low power network technologies. In fact, it can be considered as one of the most efficient technologies for the Internet of Things (IoT). Indeed, LoRaWAN offers long range, low-power, and low-data-rate. However, it faces diff rent challenges such as availability, authentication and integrity attacks that were presented recently. One of the dangerous attacks is a replay attack in the Activation by Personalization (ABP) that can lead to a selective denial-of-service on individual end devices. In this thesis we aim to strengthen the IoT security measures in the ABP or Activation by Personalization joint procedure during key generation and exchanging process, by introducing a modification on the key management exchange of both the network and application keys.
