Abstract:

5G wireless communication technologies are considered as the key enabler of various IoT applications, including autonomous driving, smart manufacturing, virtual reality, smart healthcare, etc. Although there is significant ongoing work on the development of advanced 5G wireless communication techniques, such as mmWave (millimeter wave) and massive MIMO for communication performance enhancement, the security aspects of these 5G wireless communication techniques have not been well explored. This talk discusses the potential of using physical layer properties of mmWave massive MIMO communication for serving critical security functions, i.e., authentication and shared secret key generation. Our study has found that the uniqueness of beam patterns emitted by mmWave devices can be used to identify different mmWave transmitters. The reciprocity of virtual channel information can be applied to generate a shared secret key between mmWave devices under low SNR. In the end of this talk, future research directions on physical layer security of 5G and beyond will be discussed.
