Efficient Physical Layer Group Key Generation in 5G Wireless Networks
CNS, pp. 1-9, 2020.
We investigate group secret key generation in 5G mmWave Massive MIMO networks and intend to improve the efficiency of channel probing for group key generation. In this paper, a new channel probing strategy for star-topology networks is proposed, which relies on the multiplexing of downlink probing signals, enabled by the hybrid precoding....More
