context: NOTE: If the OMA DRM V2.0 DCF [15] specification is upgraded, these upgrades do not apply for the present document. When it is required to protect MBMS download data, OMA DRM V2.0 DCF as defined in OMA DRM V2.0 DCF [15] shall be used. MBMS download data are therefore indicated by minor version 0x00000002 in a DCF. OMA DRM Rights Objects are not utilized. Instead, encryption and authentication keys are generated from MTK. For integrity protection, an OMADRMSignature as specified below is attached inside the optional Mutable DRM information box ('mdri') of the DCF. The OMADRMSignature Box is an extension to OMA DRM V2.0 DCF for use by MBMS, and is defined as follows: aligned(8) class OMADRMSignature extends Fullbox(âodfsâ, version, flags) { Unsigned int(8) SignatureMethod; // Signature Method Char Signature[]; // Actual Signature } SignatureMethod Field: NULL 0x00 HMAC-SHA1 0x01 The range of data for the HMAC calculation shall be according to section 5.3 of OMA DRM V2.0 DCF [15].
