TReX User Manual v15.30 Firmware

“Duplicate Reject” prevents repeat playback attacks where a malicious or nuisance user could
record transmissions, and retransmit in an attempt to defeat security. Duplicate reject examines
the encrypted time stamp in a transmission and only allows more recent time-stamped
messages to be processed. Using this method all historic repeated messages from a transmitter
can be rejected.

Note: The transmitter system DATE and TIME must be set and operating for the secure
duplicate reject feature to work. The receiving TReX does NOT need to have the time set if it
does not transmit.

When correctly configured, the padlock icon is displayed in the top icon bar. RX screen
content is normally readable if correctly decrypted.
