Abstract
One embodiment of the present invention sets forth a technique for decrypting digital content in a secure environment. The technique includes the steps of receiving a digital rights management (DRM) license associated with a first frame of encrypted data from a DRM server, where the DRM license includes a decryption key for decrypting the first frame of encrypted data, transmitting the DRM license to a secure content playback pipeline for storage, and transmitting the first frame of encrypted data to the secure content playback pipeline for decryption, where, in response to receiving the first frame of encrypted data, a trusted processing entity within the secure content playback pipeline decrypts the first frame of encrypted data based on the decryption key included in the DRM license to generate a first set of decrypted data and store the first set of decrypted data in a secure memory space.
