Trusted Hardware Acceleration for Malicious-Secure Function Secret Sharing

Function secret sharing FSS underlies two-party private inference and private information retrieval, with cost dominated by generating, moving and evaluating distributed point function DPF keys. A trusted GPU-integrated distributed function accelerator DFA removed key movement by generating and...

Efficient Private Inference Based on Helper-Assisted Malicious Security Dishonest Majority MPC

Private inference based on Secure Multi-Party Computation MPC addresses data privacy risks in Machine Learning as a Service MLaaS. However, existing MPC-based private inference frameworks focuses on semi-honest or honest majority models, whose threat models are overly idealistic, while malicious...
