6.6.4 The Keys Applied
The following shows in diagrams the keys as they are applied during a
DCI Mastering on CLIPSTER and a play-out by the D-Cinema player.
The Keys on CLIPSTER
This diagram shows the keys applied on a DVS DCI Mastering system:
AES key – Generated automatically by CLIPSTER
Encryption Key – Certificate with public key must have been sent
to you by the theater (i.e. the public key of a
specific D-Cinema player)
– Has to be set on CLIPSTER
Signing Key – Normally, you must provide this key pair (i.e.
your own Signing Key) and its private key has
to be set on CLIPSTER
– Alternatively, you may use a system specific
Signing Key provided by DVS if it meets your
safety requirements
– The public key of the Signing Key will be
attached to the extra files of the DCP and is
thus delivered with the DCP automatically
Self KDM – Similar to the Encryption Key
– Public key file is available on CD-ROM or in the
installation directory of the respective DVS sys-
tem
– Requires a different setting than the Encryption
Key in the DVS software
See chapter “Using the DCP and Self KDM” on
page 4-1.
Please note that the explanations of the keys at the recipient
