Abstract

See full text

Systems and methods for secure delivery of output surface bitmaps to a display engine. An example processing system comprises: an architecturally protected memory; and a processing core communicatively coupled to the architecturally protected memory, the processing core comprising a processing logic configured to implement an architecturally-protected execution environment by performing at least one of: executing instructions residing in the architecturally protected memory and preventing an unauthorized access to the architecturally protected memory; wherein the processing logic is further configured to provide a secure video output path by generating an output surface bitmap encrypted with a first encryption key and storing an encrypted first encryption key in an external memory, wherein the encrypted first encryption key is produced by encrypting the first encryption key with a second encryption key.
