A finger in the air guess would that it was designed like early memory stick
stuff and the security is enforced entirely in software (ie there is a
'protected' bit the driver honours 8).
I would venture the handshake is used to identify that the driver honours the
bogo DRM protocol and that is the problem. If their DRM was done right, and
enforced on the SD card they would simply have a public and a private card
initialisation scheme, the first of which refused to return sectors marked
as locked.
