I just priced laser projection keyboards. 40.00 or so. I think that’s the ”safest” option.
Presuming you have sufficient levels of assurance that no software exploits are present and no keystroke loggers etc. The only way to attack and the value of the attack being high enough (root CA compromise?) that an adversary would deploy (laser) mics.
I figure that anyone this concerned would program a coupe of rubber duckies or yubikey static mode ? Then the emitted strings would be unknown.
Also what about collecting from the screen via emissions?
- ssl-3 2y agoTapping on different points on a desk also produces sound characteristics that are unique to those points. One thing that could help to randomize that is a surface with tightly-coupled [truly] randomly-moving masses underneath, so that the resonances of the surface also change randomly. (And if done very right or very wrong, you get a free Van De Graaf generator!) --- Or: A laser projected keyboard where the keys are always shifting to different locations. (Bonus: Free psychosis!)

- DoctorOetker 2y agothats probably even worse since a laser is a coherent beam, and fingers interrupting a beam closer or further will change the spatial and temporal coherence of light emitted from the scene, thats a lot of information leakage...
