The host could provide a public encryption key to the card reader. Of
* With a tampered USB cable, there still would be attacks possible,
though different ones. That is, unless the reader can know the
identify of the host, which would again require a priori exchange,
so nothing gained.
* This is very likely not part of the existing API (PC/SC?).
