Partitioned Searchable Encryption
, 2021 Symmetric searchable encryption (SSE) allows to outsource encrypted data to an untrusted server and retain searching capabilities. This is done without impacting the privacy of both the data and the search/update queries. In this work we put forth a new flavour of symmetric searchable encryption (SSE):Partitioned SSE is meant to capture the cases where

Fuzzy Keyword Searchable Encryption Scheme Based on Blockchain
Information, 2022 Searchable encryption is a keyword-based ciphertext retrieval scheme, which can selectively retrieve encrypted documents on encrypted cloud data. Most existing searchable encryption schemes focus only on exact keyword searches and cannot return data of ...

Searchable encryption scheme based on attribute policy hiding in a cloud environment
网络与信息安全学报, 2022 Attribute-based searchable encryption technology can achieve fine-grained access control of data, but the existing searchable encryption scheme, keyword search, access control and file encryption are basically performed separately, causing the attacker ...

Multi-Keyword Searchable Identity-Based Proxy Re-Encryption from Lattices
Mathematics, 2023 To protect the privacy of cloud data, encryption before uploading provides a solution. However, searching for target data in ciphertext takes effort. Therefore, searchable encryption has become an important research topic.

Quantum Searchable Encryption for Cloud Data Based on Full-Blind Quantum Computation [PDF]
IEEE Access,2019.7:p.186284-186295, 2023 Searchable encryption (SE) is a positive way to protect users sensitive data in cloud computing setting, while preserving search ability on the server side, i.e., it allows the server to search encrypted data without leaking information about the plaintext data. In this paper, a multi-client universal circuit-based full-blind quantum computation (FBQC)

Leakage-Abuse Attacks Against Forward and Backward Private Searchable Symmetric Encryption [PDF]
Conference on Computer and Communications Security, 2023 Dynamic searchable symmetric encryption (DSSE) enables a server to efficiently search and update over encrypted files. To minimize the leakage during updates, a security notion named forward and backward privacy is expected for newly proposed DSSE ...

Expressive Attribute-based Searchable Encryption Scheme in Cloud Computing [PDF]
Jisuanji kexue, 2022 Searchable encryption technology can realize keyword search without decrypting the data,and thus well protects user'sprivate information.Aiming at the problem that most current searchable encryption schemes cannot support user-defined search strategies ...

Verifiable dynamic searchable encryption
TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2019 Using regular encryption schemes to protect the privacy of the outsourced data implies that the client should sacrifice functionality for security. Searchable symmetric encryption (SSE) schemes encrypt the data in a way that the client can later search and selectively retrieve the required data. Many SSE schemes have been proposed, starting with static
