Description
Document Tips

This specification defines a "Key Delivery Message" (KDM) for use in Digital Cinema (D-Cinema) systems.The KDM has been designed to deliver security parameters and usage rights between D-Cinema contentprocessing centers (e.g. from post production to distribution, or from distribution to exhibition). The KDMcarries fundamentally three information types:

Content keys for a specified Composition Play List (CPL).
Content key parameters -- primarily the permitted key usage date/time window.
The Trusted Device List (TDL) which identifies equipment permitted to use the content keys.

The KDM is based on the D-Cinema generic Extra-Theater Message (ETM) format [ETM]. It uses XML torepresent the information about the content decryption keys and TDLs, and provides security usingstandardized XML encryption and signature primitives. The KDM message uses X.509 digital certificates,specified in [D-Cinema Digital Certificate], to provide authentication and trust.
