1. A key fob-control unit pairing device, comprising:
- a transceiver to transmit and receive signals;
a memory to store a key fob identification (KFID) and a control unit identification (CUID); and
a processor coupled to said transceiver and memory to;
perform an identification (ID) authenticated key agreement protocol based on the KFID to generate a common secret encryption key shared between the key fob and the pairing device;
authenticate the key fob by generating an encrypted CUID using the common secret encryption key generated from the identification (ID) authenticated key agreement protocol; and
transmit the encrypted CUID to the key fob.
