Abstract
Methods, systems, and devices for preconfigured reference signal resources for secret key extraction are described. In some examples, a user equipment (UE) may identify a set of resources reserved for a secret key derivation process including an exchange of reference signals between the UE and a first wireless device using the set of resources. As such, the UE may transmit a first reference signal to the first wireless device using the set of resources and may receive a second reference signal from the first wireless device in accordance with the secret key derivation process. The UE may estimate a communications channel between the UE and the first wireless device and may determine the secret key based on the communications channel in accordance with the secret key derivation process. Accordingly, the UE may communicate with a selected wireless device over the communications channel using wireless communications secured using the secret key.
