This standard presents a specification for Digital Certificates for use in D-Cinema systems. The standard defines the Digital Certificate format and associated processing rules in sufficient detail to enable vendors to develop and implement interoperable security solutions. In the D-Cinema environment, certificates have these primary applications:
• Establishing identity of security devices
• Supporting secure communications at the network layer (e.g.
TLS) or application-messagin
• Authentication and integrity requirements for Composition Play Lists (CPL) and Packing Lists (PL)
The Digital Certificate standard is based on a constrained form of the X.509v3 [X.509] format and processing rules. Only the most widely supported features of X.509v3 are used in order to give vendors a large selection of X.509v3 development toolkits and certificate issuing products. The constraints also avoid the complexity and ambiguity that often occurs in systems that use X.509v3 certificates.
