During the cold war, the Washington-Moscow "nuclear" hotline was set up with teleprinters and one-time pad keys for both directions. I imagine they had an analogue randomness key generator on both ends to generate the key material.
Presumably they're using ~Dual-EC DRBG~ some kind of quantum randomness generators these days.
