The external device reads that randomized code, processes it in some way (presumably a hash), and retransmits it to the implant.  Only if the implanted device receives what it considers the correct code, would it allow further manipulation.  Presumably, any attempt to illegitimately access such a device wouldn't be close enough to read the implant's reply signals, and thus couldn't proceed further.

IMHO even if you get perfect info security (which is impossible),
this will be just a small step.

Humans are screwing the climate and the food with dangerous
food supplements. In the long term this might extinguish
humans in its present form.

Heard that in Australia skin cancer is major concern,
closely related to the Sun and there a lot of food supplements
(locally we call them "E"-s) are forbidden by law.

I deny being green, but judge for yourself.
