ENROLLING/SUB-ENROLLING A DIGITAL RIGHTS MANAGEMENT(DRM) SERVER INTO A DRM ARCHITECTURE

摘要

A Digital Rights Management (DRM) system has a plurality of DRM servers performing DRM functionality and an entering DRM-E server is enrolle d into the system by an enrolling DRM-R server such that the entering DRM-E server is to be trusted within the system. The DRM-E server sends an enrollment request to the DRM-R server including a proffering identification and a publ ic key (PU-E). The DRM-R server validates the proffering identification, and, if th e request is to be honored, generates a digital enrollment certificate with (P U- E) for the DRM-E server to enroll such DRM-E server into the DRM system. The now- enrolled DRM-E server with the generated enrollment certificate is able to emplo y same to issue DRM documents within the DRM system.
