Trusted Device List (TDL)
The Goal of the TDL is to maintain timely and accurate information on participating auditoriums so that participating
subscribers can obtain information needed to issue KDMs. The TDL has several data sources: Device manufacturers,
Exhibitors, Deployment Entities, Integrators, Service Providers (interacting with Exhibitors), regional authorities and
Support.
Public Key Infrastructure (PKI)
PKI is a framework for creating a secure method for exchanging information based on public key cryptography. The
foundation of a PKI is the certi
fi
cate authority (
CA
), which issues digital certi
fi
cates that authenticate the identity of or-
ganizations and individuals over a public system such as the Internet. The certi
fi
cates are also used to sign messages,
which ensures that messages have not been tampered with.
*.pem
Privacy-enhanced Electronic Mail. File format used to distribute digital signed certi
fi
cates. Base64 encoded DER
certi
fi
cate, enclosed between "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----"
Key Delivery Message (KDM)
The security key for each movie is delivered in a unique KDM for each digital cinema server. The security key is
encrypted within the KDM, which means that the delivery of a KDM to the wrong server or wrong location will not work,
and thus such errors cannot compromise the security of the movie. The KDM is a small
fi
le, and is typically emailed to
the exhibitor. To create the correct set of KDMs for a site requires knowledge of the digital certi
fi
cate in the projection
system´s media block.
