Securing 5G HetNets Using Mutual Physical Layer Authentication.

The upcoming 5G ultra wideband mobile network is expected to provide a fundamental framework for a huge number of devices, which indicates the presence of dynamical users join and leave events. Due to highly heterogeneous architecture, it is crucial to address security in 5G HetNets. In this paper, we focus on presenting a mutual physical layer handover authentication approach for software-defined networking (SDN) assisted 5G HetNets. The legitimacy of user equipment (UE) and access points (AP) are both verified based on extracted physical layer characteristics of wireless channel links with the help of base station (BS). Furthermore, a verification is employed to enhance authentication performance. The parameters of are discussed in our simulations and Figure of Merit (FoM) is applied in the simulation to evaluate the performance of proposed authentication scheme.
