You receive a call from an unknown number and they tell you they’ve kidnapped your wife. They then give her the phone so you can hear her but she didn’t do it through Signal so she’s obviously not your wife so you just hang up.
And that’s not how you establish a PKI or implement AE (authenticated encryption).
When I send a voice message e.g. I don’t verbally sign it, that’s actually part of KE (key exchange) protocol.
Same applies to non encrypted, authenticated communication of course.
And in case you are talking about physical face to face communication: I think you’d recognize your family and friends without the help of cryptography.
Edit: if you have any question, feel free to ask! Maybe I misunderstood you? Then I’m sorry
We don’t need code words, we need a proper PKI (public key infrastructure) for authenticated communication.

You can use this to your benefit though
Instant win

Yeah, I wouldn’t recommend doing that.

That’s what the article is about though, voice messages can now be spoofed. It happened to one of my friend’s parents
