Secure Multi-Party Sampling over Joins

Summary: First efficient MPC protocol for sampling over joins, enabling approximate relational analytics without revealing inputs or metadata (e.g., degrees, join sizes). Near-linear complexity; supports multi-way joins, comparisons, group-by, with large speedups over secure join-then-sample baselines. (summarized by gpt-5.4-mini on May 27 2026)
