Even in a controller card, it's very easy to at least do some Caesar cipher or anything simple like that. They could even do something a little more complex without much troble.
- tptacek 18y agoI'm not sure what the security advantage of ROT13 is.
- hhm 18y agoI didn't say ROT13, it could be ROTx, or it could have a variable x (as with a big key), whatever... the advantage would be to make it slightly more difficult to find the meaning of the numbers in the card. I know security by obscurity doesn't work, but it's better than nothing.
- tptacek 18y agoI think it would have been even worse for FasTrak if Nate had got up on stage and said that they tried to pass XOR off as encryption. Then the story would not only be negligence, but also incompetence. There's a plausible story you can tell for why FasTrak isn't secured at all.
- hhm 18y agoYou are right.
