Forward and Backward-Secure Range-Searchable Symmetric Encryption
Jiafan Wang, Sherman S. M. Chow · DOAJ (DOAJ: Directory of Open Access Journals) · 2022
Dynamic searchable symmetric encryption (DSSE) allows a client to query or update an outsourced encrypted database. Range queries are commonly needed. Previous range-searchable schemes either do not support updates natively (SIGMOD’16) or use file indexes of many long bit-vectors for distinct keywords, which only support toggling updates via homomorphically flipping the presence bit. (ESORICS’18).
