Practical Dynamic Searchable Encryption with Small Leakage [PDF]

open access: yesProceedings 2014 Network and Distributed System Security Symposium, 2014
In this paper we revisit the DSSE problem. We propose the first DSSE scheme that achieves the best of both worlds, i.e., both small leakage and efficiency. In particular, our DSSE scheme leaks significantly less information than any other previous DSSE construction and supports both updates and searches in sublinear time in the worst case, maintaining ...

Efficient dynamic searchable encryption scheme for conjunctive queries based on bidirectional index

open access: yesTongxin xuebao, 2022
To solve the problems of complicated operation, information leakage, and inflexible query method in the update process of existing dynamic searchable encryption scheme, an efficient dynamic searchable encryption scheme (named BPC-DSSE) for conjunctive ...

Efficient Dynamic Searchable Encryption with Forward Privacy [PDF]

open access: yesProceedings on Privacy Enhancing Technologies, 2018
Abstract Searchable symmetric encryption (SSE) enables a client to perform searches over its outsourced encrypted files while preserving privacy of the files and queries. Dynamic schemes, where files can be added or removed, leak more information than static schemes.

An Efficient Two-Server Ranked Dynamic Searchable Encryption Scheme

open access: yesIEEE Access, 2020
Searchable encryption (SE) allows users to search over encrypted data without decrypting. In most existing SE schemes, server returns all matched files without relevance ranking, and the update mechanism are suffering with high communication and ...

Attribute-based multi-keyword searchable encryption scheme based on counting Bloom filters

open access: yesDianxin kexue, 2023
To address the problems of low retrieval efficiency of searchable encryption scheme under traditional public key cryptosystem, high storage overhead of keyword index, and index does not support dynamic update, based on the good space and time efficiency ...

Dynamic Volume-Hiding Encrypted Multi-Maps with Applications to Searchable Encryption

open access: yesProceedings on Privacy Enhancing Technologies, 2023
We study encrypted storage schemes where a client outsources data to an untrusted third-party server (such as a cloud storage provider) while maintaining the ability to privately query and dynamically update the data. We focus on encrypted multi-maps (EMMs), a structured encryption (STE) scheme that stores pairs of label and value tuples.

Pindex: Private multi-linked index for encrypted document retrieval.

open access: yesPLoS ONE, 2021
Cryptographic cloud storage is used to make optimal use of the cloud storage infrastructure to outsource sensitive and mission-critical data. The continuous growth of encrypted data outsourced to cloud storage requires continuous updating.

Forward Secure Conjunctive-Keyword Searchable Encryption

open access: yesIEEE Access, 2019
Searchable symmetric encryption (SSE) has been applied in constructing secure cloud storage for its simplicity, high-efficiency, and practicality. Recent works show that forward privacy has become a fundamental property required for SSE, and several ...

Shedding Light on Blind Spot of Backward Privacy in Dynamic Searchable Symmetric Encryption

open access: yesIEEE Access, 2023
Dynamic searchable symmetric encryption (DSSE) enables users to outsource their data while retaining the capability to search and update on the encrypted database. Although various DSSE schemes have been proposed to achieve higher efficiency and stronger
