2.2.1.6 Cryptographic Characteristics

  • Article

ECC keys: Windows Media Digital Rights Management (WMDRM): MTP Command Extension protocols use 160 bit ECC keys as defined in [MS-DRM] section 2.2.1.3.

ECC signature creation: MSDRM signatures are created using ECDSA [X9.62] over curve ECC1. This algorithm is defined in its entirety in [IEEE1363]. The ECC1 curve is specified in [MS-DRM] section 2.2.1.2.

WMDRM Certificates: WMDRM certificates are used as specified in [MS-DRM] in section 2.2.2.

Cryptographic parameters: This protocol uses cryptographic parameters specified in [MS-DRM] section 2.2.1.2.
