英文名称：Digital cinema (D-cinema) packaging — Part 6: MXF track file essence encryption
发布日期：2008-07
标准范围
This standard defines the syntax of encrypted D-Cinema non-interleaved MXF frame wrapped track files andspecifies a matching reference decryption model. It uses the AES cipher algorithm for essence encryptionand, optionally, the HMAC-SHA1 algorithm for essence integrity. The D-Cinema track file format is designedto carry D-Cinema essence for distribution to exhibition sites and is specified in the Sound and Picture TrackFile specification.This standard assumes that the cryptographic keys necessary to decrypt and verify the integrity of encryptedTrack Files will be available upon demand. More precisely, if does not specify the fashion with whichcryptographic keys and usage rights are managed across D-Cinema distribution and exhibition environmentsIn addition, this document does not address, but does not preclude, the use of watermarking, fingerprinting orother security techniques to provide additional protection The scope is limited to D-Cinema and dees notdefine a generic MXF encryption framework.
