OT: USB key with hardware encryption?

[Richard Höchenberger]

Hello,

so, it happened again. Since I have neither a scanner nor printer at
home, I had to scan and print some important documents (CV, copies of
some certificates) at my workplace. Scanned them right onto a USB key,
which of course had to be unencrypted and formatted with a FAT file system.

When I got back home, the key with all its sensitive data was gone.
Probably left it somewhere on the train, I don't know.

This is not the first time this has happened to me. I usually encrypt
every mass storage device in my possession; but I cannot use full disk
encryption software at my workplace because of access restrictions.
Also, the standalone scanners require plain FAT, as mentioned earlier.

I was wondering whether there are USB flash memory devices available
that support some kind of hardware encryption, i.e. maybe some USB key
with a keypad, which only exposes a (transparently) decrypted filesystem
to the host computer.

I am using Linux, OS X, and Windows.

Do you have any thoughts and recommendations on this issue?
