LoRaWAN possible attacks, proposed countermeasures and enhanced solution

Abstract

The internet of things (IoT) is pervading our lives to provide a comfortable and smarter human living space by connecting sensors and objects directly with one another without human intervention. The requirements for the deployment of millions of IoT objects are increasing rapidly with a major security concern. To face this challenge, security solutions on cryptography might be used. In this paper, we investigate one of the widespread IoT security solutions, that is LoRaWAN technology. We evaluate its security by gathering the possible attacks. Afterwards, we propose an enhanced LoRaWAN architecture that faces these attacks. We evaluate the proposed solution in terms of security and performance parameters and compare it to existing solutions.
