Establishing a secure channel between a device and user mode application

I don't suppose that there are any cryptographic services available from
kernel mode that would permit the establishment of a secure channel between
a device and a user mode application. I see a few cryptic remarks on COPP
in the DDK but that seems only to apply to video drivers.

Regards,

George.

Why encrypt this stuff? Is it going via the hardware wire which is subject
to possible eavesdropping?

no, there is not. any other driver could snoop the exchange, so it would
not be that secure to begin with.

If it were so, what is the point of DRM, all these "certified paths" etc?

Pavel,

You are supposed to ask that :-)

Check out the work being done in the Trusted Computing Group,
www.trustedcomputinggroup.org.

Gary,

Thanks for responding. I'm not sure how this link helps. Is there a more
specific link?

Regards,

George.

TCG is working on specifications for trusted computing. The cove such things
as Storage, such as the FDE drives being released by Hitachi and Seagate, as
wellas TPMs, infrastructure, Software Stack, etc. It a resource you need to
check since as I understood your question TCG is spec'ing it.

I guess you know the answer. The point is to make it a bit harder for honest
people to copy DRM content.
