There is a dedicated authentication coprocessor, to which the communications will be authenticated, so yes.

The thing you're talking about ("secure enclave") is not present in the phone the FBI are trying to attack.

Also, the Secure Enclave co-processor is on-die, so there will be no need to authenticate or encrypt communications with it.
