摘要

Methods and systems are provided to protect Cryptographically Secure Content in connection with a Graphics subsystem of a Computing device. The techniques are implemented to Encrypt the contents of Video Memory, so that unauthorized software cannot get access to the same significant, thereby maintaining confidentiality.In addition, a mechanism is provided for the detection of Tampering, so that Knowledge exists when data has been altered in some way, thus maintaining the integrity.Several forms of realization, the contents are encrypted overlay surfaces and / or Memory instructions, and / or the GPU is capable of operating on the encrypted content, at the same time that prevents their availability for Parties, devices or software not reliable.
