Examples described herein relate to a system that includes a central processing unit; a trusted execution environment (TEE); and a graphics processing system. In some examples, the central processing unit is to process homomorphically encrypted video game object data. In some examples, the TEE is to transpose the processed homomorphically encrypted object data to a second encryption format. In some examples, the graphics processing system is to perform a graphics processing pipeline operation on the object data in the second encryption format and provide rendered image data of the video game to a buffer. In some examples, the TEE is to receive homomorphic decryption keys and transpose the processed homomorphically encrypted object data to a second encryption format based on the homomorphic decryption keys. In some examples, the system is to inform a gaming server of a change to object data received from the gaming server to identify cheating.

Anti-cheat game technology in graphics hardware

Methods, apparatuses and system provide for technology that interleaves a plurality of verification commands with a plurality of copy commands in a command buffer, wherein each copy command includes a message authentication code (MAC) derived from a master session key, wherein one or more of the plurality of verification commands corresponds to a copy command in the plurality of copy commands, and wherein a verification command at an end of the command buffer corresponds to contents of the command buffer. The technology may also add a MAC generation command to the command buffer, wherein the MAC generation command references an address of a compute result.

Graphics security with synergistic encryption, content-based and resource management technology

Examples described herein relate to a system that after decoding of video by the first device, provides a memory address of decoded video in the memory device to a second driver for a second device and perform a second device driver that causes the second device to access the decoded video directly from a translation of the memory address of the memory device, wherein the second device is to access the decoded video with memory properties of the decoded video and decompression information of the decoded video. In some examples, the first device comprises one or more of: a graphics processing unit integrated with a central processing unit (CPU), a discrete graphics processing unit, or a video decoder accelerator. In some examples, the second device comprises one or more of: a graphics processing unit integrated with a central processing unit (CPU) or a discrete graphics processing unit. In some examples, the memory properties of the decoded video comprise swizzle information. In some examples, decompression information of the decoded video comprise a decompression scheme or decompression key.

Processing of data by multiple graphic processing devices

A method and system is provided for securing content from malicious shaders. The method includes determining the content the shader is to execute. A signature of the shader is verified in response to the shader attempting to execute on protected content. In response to the shader being verified, it is verified that the shader has not been modified. The shader is executed in response to not being modified.
