         | Maybe they wanted to decrypt NATO radio messages?

           | being part of NATO, can't they just get a copy of the keys
           | from somebody? or is it a case of "they might turn on us,
           | better keep an ace"?

       | So you need 2 hours of both encrypted and unencrypted data at
       | same time to make this attack work, is this feasible? And if you
       | just flip the switch on devices to use more bits in the
       | encryption the attack becomes unfeasible. Piss poor that NATO
       | never replied to them.

       | I am not a cryptography or digital radio expert, so grain of salt

       | 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?
