Explore a conference talk from USENIX ATC '23 that introduces SAGE, a software-based attestation mechanism for GPU execution. Delve into the growing need for integrity and privacy in computation using accelerators like GPUs, especially in security-critical and sensitive domains. Discover the advantages of a software-only approach to trusted GPU execution, including its ability to complement hardware-based approaches, operate on GPUs without specific hardware support, and achieve security without relying on embedded hardware secrets. Learn about SAGE's capabilities in enabling secure code execution on NVIDIA GPUs of the Ampere architecture (A100), providing code integrity and secrecy, computation integrity, and data integrity and secrecy, even in the presence of malicious code on both GPU and CPU. Gain insights into the practical applications of SAGE for executing code in a trustworthy manner on GPUs without specific hardware support.
