Searchable symmetric encryption (SSE) has been launched to allow safe outsourcing of encrypted databases to cloud storage, whereas sustaining searchable options. Of the varied SSE schemes, most assume the server is sincere however curious, whereas the server could also be trustless in the true world.
Contemplating a malicious server not actually performing the queries, verifiable SSE (VSSE) schemes are constructed to make sure the verifiability of the search results. Nevertheless, current VSSE constructions solely deal with single-keyword search or incur heavy computational value throughout verification.
To deal with this challenge, a analysis staff led by Joseph Okay. Liu revealed their new analysis on 02 April 2022 in Frontiers of Laptop Science.
The staff proposes a brand new VSSE building supporting conjunctive key phrase queries, which will be handled as an enchancment of a latest VSSE answer. The proposed VSSE scheme relies on a privacy-preserving hash-based accumulator, leveraging a well-established cryptographic primitive, Symmetric Hidden Vector Encryption (SHVE). The VSSE scheme permits each correctness and completeness verifiability for the outcome with out pairing operations, thus significantly lowering the computational value within the verification course of.
