This is a really interesting question. But, does this really matter got
an USB device? If there is a program on your computer, which interceps
the communication, the security of you system is already broken. So the
decrypted file itself could/would be read by a third party. The session
key is, in this moment, the least problematic thing on your system.
But, regardless of this, it is an interesting question.
