In a sense, graphics cards are the root-of-trust for PC-based DRMs (as they implement the necessary components such as HDCP authentication), not the TPM (which is useless for this task). In fact, PlayReady (which is Microsoft's DRM solution) does this exact thing: https://learn.microsoft.com/en-us/windows/uwp/audio-video-ca... (...or use things such as the already-dead Intel SGX, which never touched TPMs at all) |
