I would expect it to be similar but i don't really know CSS.
You can take a look at dumpHD as a sample implementation. KenD00 has recently released the source code.

To obtain the volume id from a disc the player must present a valid certificate which the drive will challenge. The certificates can be revoked. A patched drive doesn't require authentication to access protected data. So having a patched drive can be compared with knowing the ECDSA private key used to sign the certificates. It's certainly possible to provide patches for drives from other vendors too.
