Internet of things security issues in lorawan and bluetooth low energy

The Internet of Things (IoT) technologies are attracting the interest of scientific and industrial communities given the huge number of applications that can be designed with energy-limited devices connected to the Internet. LoRaWAN (Long Range Wide Area Network), a data-link layer with long range, low power, and low bit rate, appeared as a promising solution for IoT in which, end-devices communicate with gateways through a single hop at long distances. On the other side, the short-range IoT can leverage the potentialities of Bluetooth Low Energy (BLE) in its mesh network setting to interconnect, in proximity, multiple devices. Both technologies are already hitting a large market, but there are still several issues dealing with their security. This chapter is dedicated to the analysis of selected security issues affecting IoT networks and specifically low-power wireless systems such as LoRaWAN and BLE.
