Update-Sensitive Structured Encryption with Backward Privacy
IACR Cryptology ePrint Archive
Many recent studies focus on dynamic searchable encryption (DSE), which provides efficient data-search and dataupdate services directly on outsourced private data. Most encryption schemes are not optimized for update-intensive cases, which say that the same data record is frequently added and deleted from the database. How to build an efficient and secure DSE scheme for update-intensive data is still challenging. We propose UI-SE, the first DSE scheme that achieves single-roundtrip interaction,dblp:journals/iacr/WuWL21 fatcat:d3soatc2rzboplwpuygnaoldiq
