ccAI: A Compatible and Confidential System for AI Computing

Confidential xPU computing has emerged as a prominent technique for effectively securing users' AI computing workloads on heterogeneous systems equipped with xPUs.Although the industry adopts this technology in cutting-edge hardware (e.g.NVIDIA H100 GPU) to safeguard high-performance AI computing, most clouds still rely on legacy xPUs and suffer from data leakage problems.
