How SMPC Query Execution can be sped up through Efficient and Flexible Intermediate Result Size Trimming
Summary: Reflex introduces composable Resizers that trim intermediate results between MPC operators, enabling per-operator/query security–performance tuning via controlled leakage. Demonstrated speedups reach 200× over fully oblivious execution and 7× over prior methods with equivalent guarantees. (summarized by gpt-5.6-luna on Jul 24 2026)
