Doppio: Communication-Efficient and Secure Multi-Party Shuffle Differential Privacy
Summary: Introduces AMP-SDP, a secret-shared intermediary architecture that decentralizes trust in shuffle DP while reducing online communication and hardening against shuffler compromise and poisoning. Doppio extends shuffle DP to flexible analytics and outperforms Network Shuffling. (summarized by gpt-5.6-luna on Jul 24 2026)
