Risk: you have the encrypted USB stick but have no PC. Will
a "locum" PC have the correct software to do the decryption
functions in order to read the stick or does the stick
itself provide such software
Risk: you lose the stick - is the encryption strong enough
to protect the data; a weak password can compromise the stick
Risk: you yank the stick out of the PC before properly
unmounting it; this can corrupt the data format and ruin the data
*IF* you can encrypt your home directory and then keep all
your data in that home directory, I think that you are quite
safe travelling with a PC.
Here is one example that got me: I stored encrypted data on my
iPod and went traveling. When I plugged the iPod into a friend's
PC in Germany, the data could not be read. I forgot that the file
system used on the iPod was HFS for the Mac and that Windows
cannot read such a file system. In this case there is no good
solution since the Mac forces you to use the HFS file system
when the iPod is connected to a Mac.
The same problem does not occur with memory sticks since they all
use the FAT32 file system, even Macs.
