Content Protection for recordable Media (CPrM)
❖
CPRM is a mechanism that ties a recording to the media on which it is recorded. It is supported by some
HDD & DVD RECORDERs, but not by many DVD players. Each blank recordable DVD has a unique 64-bit
media ID etched in the BCA. When protected content is recorded onto the disc, it can be encrypted with a
56-bit C2 (Cryptomeria) cipher derived from the media ID.
During playback, the ID is read from the BCA and used to generate a key to decrypt the contents of the disc.
If the contents of the disc are copied to other media, the ID will be absent or wrong and the data will not be
decryptable.
