Registration method between rights issuers and domain authorities for digital rights managements on wired/wireless environment and method for implementing SCE function using the registration method

摘要

A method for registering a Domain Authority (DA) and a Rights Issuer (RI) for Digital Rights Management includes exchanging information between the DA and the RI. The DA and RI are registered by the exchanging of information before executing other protocol, and the method for registering can be incorporated into the following methods for implementing Digital Rights Management (DRM) with Secure Content Exchange features: (1) acquiring user domain Rights Objects (RO) by a DRM agent; (2) using the user domain RO by a 2.0 DRM agent; and (3) using imported user domain RO by a 2.0 DRM agent.
