link between the key source and a key manager; sending, via the second link, the first keyfrom the key source to the key manager; encrypting, by the key manager, using the firstkey, a second cryptographic key; sending, by the key manager, to the ECU, the encryptedsecond key; and decrypting, by the ECU, using the first key, the encrypted second key,thereby providing the ECU with the second key.
