Scope

This part of the "Digital Cinema Packaging" standard specifies the encryption syntax for non-interlaced MXF frame-wrapped track files of digital movies that comply with GY/T 293.1—2015, as well as a corresponding reference decryption model. This syntax uses the AES encryption algorithm to encrypt basic data and, as needed, verifies the integrity of the basic data using the HMAC-SHA1 algorithm. This part assumes that the keys required to decrypt and verify the integrity of encrypted track files will be provided as needed. It does not specify the management method of keys and key usage rights in digital movie distribution and screening environments, nor does it involve the use of watermarks, fingerprints, or other security technologies to provide additional protection. It does not define a universal MXF encryption framework. This part is applicable to digital cinema packaging.
