Abstract: Systems, methods, and computer-readable media are provided for signing and executing graphics processing unit (GPU) commands. In some examples, a method can include receiving, by a GPU, one or more commands including one or more verification signatures generated using a processor, each verification signature of the one or more verification signatures including a first value generated based on the one or more commands; generating, by the GPU, one or more additional verification signatures associated with the one or more commands, wherein each verification signature of the one or more additional verification signatures includes a second value generated by the GPU based on the one or more commands; and determining, by the GPU, a validity of the one or more commands based on a comparison of the one or more verification signatures and the one or more additional verification signatures.
