i wonder how much bandwidth is required for the administration to remain in contact with washington while abroad. it must be someones job to decide how large of a one time pad to order up from the nsa before air force one departs.
- sorbus 16y agoGiven how cheap storage is now, I wouldn't be surprised if they just had a few thousand >4GB SD or microSD cards, each labelled with a number, and randomly chose which one to carry each time - or if they carried a bunch of them around in a briefcase. Assuming that they're using one time pads, that is.
