Abstract
Technologies for supporting and implementing multiple digital rights management protocols on a client device are described. In some embodiments, the technologies include a client device having an architectural enclave which may function to identify one of a plurality of digital rights management protocols for protecting digital information to be received from a content provider or a sensor. The architectural enclave select a preexisting secure information processing environment (SIPE) to process said digital information, if a preexisting SIPE supporting the DRM protocol is present on the client. If a preexisting SIPE supporting the DRM protocol is not present on the client, the architectural enclave may general a new SIPE that supports the DRM protocol on the client. Transmission of the digital information may then be directed to the selected preexisting SIPE or the new SIPE, as appropriate.
