(registered 2007-06-13, last updated 2015-03-05) Name : Uwe Rauschenbach Email : uwe.rauschenbach&nokia.com MIME media type name : Application MIME subtype name : Vendor Tree - vnd.oma.drm.risd+xml Required parameters : none Optional parameters : none Encoding considerations : binary This media type may require encoding on transports not capable of handling binary. Security considerations : Rights Issuer services carry Rights Objects, Registration data and Certificate Chain Updates in messages over broadcast channels. BCAST Rights Issuer Service Data shall be passive, and do not generally represent a unique or new security threat. Some messages contain confidential and security critical fields. These are encrypted using AES-128-CBC, and are authenticated using HMAC-SHA-1-96 as described in the OMA BCAST specification referenced below. That means, the security of such critical fields is provided by the type itself and does not have to be provided externally. Furthermore, in sharing any kind of data, there is some risk that unintentional information may be exposed, and that risk applies to unencrypted fields contained in Rights Issuer Service Data as well. Interoperability considerations : This content type carries BCAST Rights Issuer Service Data within the scope of the OMA BCAST enabler. The OMA BCAST enabler specification includes static conformance requirements and interoperability test cases for this content.
