That's interesting - did you implement some kind of key exchange or just check for the device ID? And which OS?
I might have exaggerated a bit, probably it's pretty easy to do in a "works on my machine" kind of way...
- adastra22 4y agoI used a simple challenge-response protocol. It asked the device to sign a message to authenticate itself. I then listened to udev announcements to lock the machine if the device was unplugged. It was more of a toy than a serious security device, and it would certainly need a lot more review before I recommend others to use it, but it was a fun exercise.
