spacex just launched a turkish communications satellite into geostationary orbit yesterday from florida. this means the operators had to send the satellite to florida first to be launched; do non-US governments usually send minders/guards with their satellites to monitor them 24/7 from delivery to launch so NSA/CIA can't add firmware goodies?
Ben explained this to me at the El Salvador conf. It's clever: basically, the offline device and some remote server have an ECDH shared secret. When the customer requests an invoice, the offline device generates it and gives a secret *encrypted to the ECDH key*. The customer sends that to the server with the payment, the server decrypts, and sends the customer back the one-time secret/pin which they enter into the offline device as proof. Neat.
