SWAT: A System-Wide Approach to Tunable Leakage Mitigation in Encrypted Data Stores
Summary: Analyzes workload-specific leakage for key-value, range and dynamic workloads and defines new security notions per workload. Swat: a provably leakage-mitigating, progressive system with tunable privacy–efficiency algorithms—~10× slower than leakage-revealing encryption and ~100× faster than zero-leakage.
