Mnemonica DCP KDMs

Mnemonica includes a fully integrated KDM management system that lets distributors and exhibitors handle the entire key delivery workflow directly within the platform — from uploading master keys to generating and distributing device-specific KDMs to cinema projectors.

The system is built around two modules that work in sequence: Managers first upload a DKDM (Distribution KDM) for each encrypted DCP, which authorizes the platform to generate keys. From there, any authorized user can create a KDM delivery — selecting the content, the target projector certificates, and the validity window — and send it directly to a recipient.

A role-based approval workflow ensures that sensitive key deliveries always go through the right channels: Managers can issue KDMs directly, while Power Guests and Guests submit requests that a Manager reviews before the key is generated.

Guides

How the two modules relate

DKDMs and KDMs operate in a clear upstream-to-downstream sequence. A DKDM is a master key provided by the content provider and held by the distributor — it never leaves the platform and is never sent to cinemas. It simply authorizes Mnemonica to derive device-specific KDMs from it. Each KDM is then generated for a specific projector certificate and a specific validity window, and delivered to the recipient cinema.

In practical terms: if a CPL does not appear in the KDM creation wizard, it almost always means the DKDM has not yet been uploaded for that asset. Always verify DKDM availability before starting a KDM delivery.
