SWAT: A System-Wide Approach to Tunable Leakage Mitigation in Encrypted Data Stores. (arXiv:2306.16851v1 [cs.CR])

Numerous studies have underscored the significant privacy risks associated
with various leakage patterns in encrypted data stores. Most existing systems
that conceal leakage either (1) incur substantial overheads, (2) focus on
specific subsets of leakage patterns, or (3) apply the same security notion
across various workloads, thereby impeding the attainment of fine-tuned
privacy-efficiency trade-offs. In light of various detrimental leakage
patterns, this paper starts with an investigation into which specific leakage
patterns require our focus respectively in the contexts of …
