info about this can be found at http://ps3wiki.lan.st/index.php/Basic_Bluray_disc_authentication_procedure
The authentication procedure itself is done through the use of a per Blu-Ray drive key pair, one being located on the drive controller itself while the other is stored encrypted in the playstation 3's EID area located on NAND.
EID area? not sure what that is, one place I think it might be inside is the registry file, although i'm not sure what setting it would be under.
Thanks for the spoon feed.
Well Im not sure what the EID area is either, but i'll read up on it.The good thing is its located in the data on the nand.If we can decrypt the data on the nands, we could swap keys no problem.
