Write an array of random values to a hard drive — terabytes of them.
Dupe the drive.
You now have a matching pair of "one-time pads" for, I have heard, the hardest form of encryption to decrypt. I would think expect there is a business already doing this.
- Someone 1y agoUsed properly, encryption using one time pads produces data streams that are indistinguishable from uniformly distributed random noise and cannot be cracked (https://en.wikipedia.org/wiki/One-time_pad https://en.wikipedia.org/wiki/One-time_pad)
- dist-epoch 1y agoIt's harder to ensure that no one messed with the drives during transport than to give a small private key to the other party.
- gblargg 1y agoYou also can't verify that the contents are genuinely random and not some re-creatable sequence by compromised generation hardware.
- cortesoft 1y agoThere aren't a ton of use cases for this that aren't met better by other cryptographic solutions.
