One could envision that the transportation of one-time pads as the only objects worth shipping between inhabited solar systems. Value per gram could be enormous.

"Our main cargo is a one-time cryptographic pad. The source is Commercial Security at Sjandra Kei; the destination is the certificants' High colony. It was the usual arrangement: We're carrying a one-third xor of the pad. Independent shippers are carrying the others. At the destination, the three parts would be xor'd together. The result could supply a dozen worlds' crypto needs on the Net ..."

Thanks for the ref. That's where I got it from. Couldn't remember if it was from "A Fire upon the Deep" or from an Ian Banks Culture series book.

Only if they're really random. See Venona.

Are these the same one time pads that have already been cracked by the NSA after the Soviets reused them?

If you reuse them, then it's not a one time pad any more, is it?

Yes, it's well known that two-time pads are very vulnerable in ways that one time pads are not.

They are still one time pads, just incorrectly used.

Even if the cryptography is sound, you also need to ensure that no user error can happen.
