    摘要: 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.

    摘要: A measurement engine generates an integrity manifest for a software program and uses it to perform active platform observation. The integrity manifest indicates an integrity check value for a section of the program's code. The measurement engine computes a comparison value on the program's image in memory and determines if the comparison value matches the expected integrity check value. If the values do not match, the program's image is determined to be modified, and appropriate remedial action may be triggered.
