摘要：
Methods and systems for protecting data that is intended for use and processed on video or graphics cards are described. In one embodiment, data that is stored in memory other than a video card memory is encrypted and transferred over a bus to the video card. The encrypted data is decrypted on the video card independent of a graphics processor unit (GPU) on the card needing to process the encrypted data. The decrypted data is stored in the video card memory.
