Security Establishment for IoT Environments in 5G: Direct MTC-UE Communications

We propose the direct communications between User Equipments and Machine Type Communication devices. Then we propose the use of the ProSe standard to extend the coverage of 5G towards IoT. To accomplish this, we present a new protocol for the key establishment without any prior trust relationship between a User Equipment and a Machine Type Communication device, building security from 5G towards the IoT. We then use the protocol along with ProSe to propose a new secure operating mode that has the potential to save energy and bandwidth by securing direct sessions between UEs and MTC devices, and at the same time increasing 5G coverage to the IoT.
