It seems like the benefits are having the device lock/wipe itself after a set amount of attempts in case of a brute force attack and not having to run software to decrypt the drive on the device you plug it into.
I included a picture of the IronKey Keypad 200 but that’s just because it’s the first result that came up when I was looking for an example. There seem to be a few other manufacturers and models out there and they probably have different features.
I am curious what do you think of them? Do you think they are useful? Do you find it more a novelty?
It was an ExplainingComputers video titled Very Useful Small Computing Things that made me think of them.
Nice just look at the most worn buttons
Damn. Dude just comes in and ends the entire discussion.
Obligatory XKCD
Do encryption in software. History taught us hard lessons about this.
I had one of the SanDisk flash drives that had some launcher thing on it and I had a password for some reason on it.
In high school, a classmate tried to guess it, 3 times and I lost everything on it forever, since it stupidly locked forever after 3 tries.
I had software projects from back then that I can never get back… including a web browser. I could have had the next Firefox…
If you’re out there, Liz: I’ll never forgive that.
Liz taught you to make backups of data you value
Hardware signing devices have lots of utility because they keep the key from ever being on the machine (which is more likely to be compomised). Think ledger or trezor for your Bitcoin. Hardware encryption devices are just really expensive and black-box ways to avoid Veracrypt.
If your encryption algorithm is secure, you have no use for automatic lock-out. If it’s not, automatic lockout won’t do much against an attacker with physical access to the device. Unless they are dumb enough to trigger the lockout AND the internal memory wipes itself sufficiently well AND/OR the attacker doesn’t have the resources to reverse engineer the device.
If your encryption algorithm is secure, you have no use for automatic lock-out.
This isn’t true. You need your algorithm and your key to be secure. If the key needs to be remembered or entered often it probably can’t be secure. So brute force protection becomes very important.
If it’s not, automatic lockout won’t do much against an attacker with physical access to the device.
This isn’t true. Yes, with enough time and effort it is possible to extract any data from any device. But in practice physical HSMs do an excellent job at raising the cost of key extraction. I would much rather have an attacker steal my Yubikey than a USB with my GPG key lying on it.
