Security survey of the IoT wireless protocols

With the increasing usage and impact of the services based on data from Internet of Things (IoT) networks, securing the sources as well as the transport of these data is crucial. In this paper, we present our survey of the security of the four widely used IoT protocols: Bluetooth Low Energy, LoRaWAN, ZigBee and Z-Wave. We discuss various vulnerabilities in the protocols and how the protocols evolved from the security point of view. The survey is a base for our future work on a secure gateway for IoT networks. In this project we are going to detect security incidents in IoT networks at the gateway connecting the IoT devices with the application servers.
