Security and Privacy Aspects in 5G Networks

The future mobile 5G networks are envisioned to support billions of devices, higher data rate, and omnipresent connectivity, with the help of a diverse set of technologies, e.g., network densification, mMIMO, mm-Wave, full-duplex radios, network slicing, visual-light communication, cognitive radio networks, device-to-device communications, machine-to-machine communications, and satellite-based communication. While 5G will assist in a wide range of applications, heterogeneous devices and technologies impose significant threats to 5G networks as compared to the previous generation of the communication networks. In this article, we discuss the need of new security techniques for 5G networks and the key research challenges related to security/privacy in 5G networks.
