his standard defines the syntax of encrypted D-Cinema non-interleaved MXF frame-wrapped track files and specifies a matching reference decryption model. It uses the AES cipher algorithm for essence encryption and, optionally, the HMAC-SHA1 algorithm for essence integrity. The D-Cinema track file format is designed to carry D-Cinema essence for distribution to exhibition sites and is specified in the Sound and Picture Track File specification.
This standard assumes that the cryptographic keys necessary to decrypt and verify the integrity of encrypted Track Files will be available upon demand. More precisely, it does not specify the fashion with which cryptographic keys and usage rights are managed across D-Cinema distribution and exhibition environments. In addition, this document does not address, but does not preclude, the use of watermarking, fingerprinting or other security techniques to provide additional protection. The scope is limited to D-Cinema and does not define a generic MXF encryption framework.
