executing a first ID authenticated key agreement protocol based on a first key to generate a second key based on the first key, the first key being associated with the first device;
receiving, by the first device, an encrypted third key, the third key being associated with the control unit, the received encrypted third key being encrypted using the second key;
decrypting, by the first device, the encrypted third key using the second key;
executing a second ID authenticated key agreement protocol based on the third key to generate a fourth key;
receiving, by the first device, an encrypted operational key from the control unit, the operational key being encrypted using the fourth key; and
after receiving, by the first device, the operational key from the control unit, erasing from the first device the third key.
