Abstract

Secret key generation (SKG) from wireless channel reciprocity has been demonstrated on WiFi, LTE, and LoRaWAN, but has never been demonstrated on 5G New Radio (NR) Sounding Reference Signal (SRS) and CSI Reference Signal (CSIRS) measurements.

Keywords

Secret key generation wireless channel reciprocity 5G New Radio Sounding Reference Signal CSI Reference Signal
