ABSTRACT:
Methods and systems for protecting data that is intended for use and processed on video or graphics cards are described. In one embodiment, encrypted data that is intended to be processed by a graphic processor unit (GPU) is received into unprotected memory portions of a video card. The encrypted data is decrypted into protected memory portions of video card. The unencrypted data in protected memory portions of the video card is encrypted into protected memory portions of the video card.
