摘要：
Disclosed are methods and devices for deriving keys for coding the contents of data frames, which are to be transmitted in a keyless entry system during an ultra-wide band ranging session between a transceiver device coupled to a base structure to be opened and closed and/or to be locked and unlocked, and a mobile transceiver device associated with the structure-coupled transceiver device.
