Brilliant suggestion. Have a TRNG or a CSPRNG (if too poor for a TRNG) choose the next layout at random for you, ideally with every keystroke. Good luck crackin

- hoosieree 3y agoEven using Vim or Emacs would add some obufsCTRL[dbiobfuscation from all the spurious keystrokes.
- segfaultbuserr 3y agoSome places use touchscreen keypads for PIN entry exactly for this reason: to allow randomization, e.g. for opening a locked door, or for authorizing a transaction.
- bee_rider 3y agoThat is interesting. I’m sure it depends on the application to some extent. I can type my pin in without looking at all, so I can cover it up while doing it. If I had to hunt and peck, it’d easier for an onlooker to observe my slower motions I think. But if I used the same machine often enough to produce wear specific to me, this randomization would be really useful.
- zootboy 3y agoI use a randomized PIN pad on my phone, and I've gotten quite used to it. I can enter my PIN almost as fast as I could on an unscrambled pad; it's definitely not hunting and pecking.
- 8note 3y agoDo they randomize the key locations though? Otherwise, you leave behind grease where your fingers touched
- segfaultbuserr 3y agoYes, the layout is randomized every time you use it.

- mdp2021 3y agoCould be done by using a device with a display - e.g. an "ereader" - to present a random keyboard layout. But, good luck being efficient typing on that. At that point, better use a different input model. Or, use techniques such as those in the article, such as random keypresses played during the actual ones.
- FireBeyond 3y agoSome banks went through a phase of this - website would present an on screen keyboard for the password field with a randomized layout. I'm sure customer frustration was huge.
