Security establishment for IoT environments in 5G: Direct MTC-UE communications
Résumé
In this paper, we propose a new protocol for the key establishment without any prior trust relationship between an UE and a Machine Type Communication (MTC) device, building security from 5G towards the IoT. We use the protocol with ProSe to increase 5G coverage and propose a new secure operating mode that has the potential to save energy and bandwidth by securing direct sessions between UEs and MTC devices.
