Perhaps you can deduce which chip is doing the encryption by
identification data transmitted by the chip down the line -- they
might identify themselves, making it impossible for you to avoid
having them figure out which pair of keys registered with the Ministry
of Truth and the Ministry of Love are to be used to listen in on your
conversation. After all, they keys are registered by the
manufacturer...

PS We all remember the Ministry of Love and the Ministry of Truth,
don't we? This proposal was, of course, created by a group spun off
from the Ministry of Peace, a.k.a. No Such Agency.
