No, this is a a breifcase full of one time pad. If you could fit 32 4 TB hard drives full of pad in the brief case that would allow you to send 128 TB in the future securely using something like an XOR one time pad. Assuming you are just sending ASCII and compress it before sending/XORing you could send a lot more then 128 TB of ASCII.
This is pretty powerful. It means that organization which and periodically move physical assets securely can send information in a manner that is secure even if quantum computers reach their full potential.
- _kst_ 13y agoWas "128 GB" a typo for "128 TB"? Incidentally, the mechanism for sharing the pad doesn't have to be 100% secure, as long as you can reliably detect any compromises. If someone opens the briefcase while it's in transit, you just generate new pads and send another briefcase. To compromise the system, an adversary has to compromise the pad in transit without being detected.
