Security of Heterogeneous Systems
Explore the security challenges of heterogeneous computing systems in this 38-minute lecture by Hoda Naghibijouybari, Assistant Professor in the Department of Computer Science at Binghamton University. Delve into the evolution from traditional to modern heterogeneous systems, focusing on microarchitectural attacks and side-channel vulnerabilities. Examine GPU architecture, the CUDA programming model, and specific security threats like website fingerprinting and inter-keystroke timing attacks. Learn about defense mechanisms, including temporal and spatial partitioning, and the GPUGuard solution. Compare integrated and discrete GPUs, analyzing their unique security implications. Gain insights into the complexities of securing CPU-GPU systems, remote cross-component attacks, and potential defense strategies for heterogeneous computing environments.
