giving a device access to EFS encrypted files

Hi,

I am developing an application that uses encrypted files which are
encrypted under EFS. I use a device API to control an MPEG decoder
card. My application can directly open the files fine, but when I call
the device API function to open the file (which I need to do), the
device cannot read the contents.

I think the device cannot open the file because it doesn't have the
rights to access EFS encrypted files. Everything works just fine if I
don't use encrypted files.

I did some research and found that all users need to have the correct
certificate and private key inorder to read the contents of EFS
encrypted files. I assume that a device would need the same to read
encrypted files.

I need to know how to assign a device (or its driver) the correct
certificate and private key.

Can someone please tell me how I can go about doing this? Or if I'm
completely off, can someone point me in the right direction?

Thanks in advance,
Kevin
