8,661,552, "Provisioning a computing system for digital rights management," assigned to Microsoft.
Various embodiments utilize hardware-enforced boundaries to provide various aspects of digital rights management or DRM in an open computing environment. Against the backdrop of these hardware-enforced boundaries, DRM provisioning techniques are employed to provision such things as keys and DRM software code in a secure and robust way. Further, at least some embodiments utilize secure time provisioning techniques to provision time to the computing environment, as well as techniques that provide for tamper-resistant storage.
