The nice thing about a OTP is that it's only used once, unlike a typical cipher. If pads are lost, well that's fine because they weren't going to be used with anyone else.
- lb1lf 6y agoTrue, but with the (used) pads you can reconstruct past messages. (Provided you intercepted those, that is.)
- jandrese 6y agoSure, but it's also easy to have a system where the pad is destroyed after it is used. This would help insure that nobody messes up and uses the same bits twice as well.
- _wldu 6y agoYou can also have a separate set of pads that decrypt the messages to something entirely different from the real messages. I'm not aware of another crypto system that allows for this. Here's an example: $ padder -d -m c2wrbumxvj8gob34mxn46pxg29a6kxnwfhcaam3en-hr-2v -p ryxrvqnlhz04icqq6eg56cuhg10vlx5dff3ba44wg6ic-kd PlainText: we-are-moving-north-and-will-attack-at-the-pass $ padder -d -m c2wrbumxvj8gob34mxn46pxg29a6kxnwfhcaam3en-hr-2v -p zifs6d9dgk36k94m9d5x77jhj277ip59gw9btmv4j7in-kc PlainText: our-group-fled-south-to-the-city-we-sailed-east
