Information-theoretically secure encryption is possible with one-time pads.
What about information-theoretically secure authentication?

It would be cool to have a communications application/library/protocol that uses this, however cumbersome it might be.

You could preshare the key by connecting two devices by cable.

That would be guessable if you had enough time and power and thus not information-theoretically secure AFAICS.
