Result-pattern-hiding Conjunctive Searchable Symmetric Encryption with Forward and Backward Privacy [PDF]

Proceedings on Privacy Enhancing Technologies, 2023
Dynamic searchable symmetric encryption (DSSE) enables the data owner to outsource its database (document sets) to an untrusted server and make searches and updates securely and efficiently. Conjunctive DSSE can process conjunctive queries that return the documents containing multiple keywords.

Searchable Encryption for Conjunctive Queries with Extended Forward and Backward Privacy

Proceedings on Privacy Enhancing Technologies
Recent developments in the field of Dynamic Searchable Symmetric Encryption (DSSE) with forward and backward privacy have attracted much attention from both research and industrial communities. However, most DSSE schemes with forward and backward privacy schemes only support single keyword queries, which impedes its prevalence in practice.

Verifiable Conjunctive Dynamic Searchable Symmetric Encryption With Forward and Backward Privacy

The Computer Journal, 2022
Abstract Dynamic searchable symmetric encryption (DSSE) with forward and backward privacy makes it possible to perform search on the outsourced encrypted database efficiently while still allowing updates under acceptable leakage. Current forward and backward private DSSE (FB-DSSE) scheme proposed by Zuo et al.
