For those without a free hour to watch, here's the slide deck?

I am not a cryptography or digital radio expert, so grain of salt and all that.

Slide 14 shows real world feasibility, I think it's safe to say that while theoretically possible it's unlikely that this creates a significant real world issue. One bit of info I don't know - how long is a set of exchanged keys used for in most situations?

Yeah I was looking for that. When I was in basic training the security of radio crypto was described as maybe a week in the field.

Any attack taking years isn't going to be operationally relevant.

I suspect this protocol was developed basically as a computational complexity trade off to keep within those sorts of boundaries.
