Abstract
Systems, apparatuses, and methods for implementing digital rights management using a GPU are disclosed. In one embodiment, a system includes at least a GPU, a security processor, and a memory. The GPU is configured to execute a first portion of a binary and detect that a second portion of the binary is encrypted. The second portion of the binary includes enhanced content that is available for purchase. If the user purchases the enhanced content, a license server generates a token specific to the security processor of the system and conveys the token to the system. Next, the security processor decrypts the second portion of the binary using the token and stores the decrypted second portion of the binary at a memory location accessible by the first processor. Then, the first processor executes the second portion of the binary.
