Updatable Multi-User Dynamic Searchable Encryption Scheme with Bidirectional Verification

Mathematics
Among searchable encryption techniques, multi-user dynamic searchable encryption (MUDSE) schemes are an important research direction. After the data owner transfers data to the cloud, it may be necessary to authorize different users to access some or all

Dynamic Searchable Encryption via Blind Storage [PDF]

2014 IEEE Symposium on Security and Privacy, 2014
Dynamic Searchable Symmetric Encryption allows a client to store a dynamic collection of encrypted documents with a server, and later quickly carry out keyword searches on these encrypted documents, while revealing minimal information to the server.

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

Dynamic Local Searchable Symmetric Encryption [PDF]

, 2022
In this article, we tackle for the first time the problem of dynamic memory-efficient Searchable Symmetric Encryption (SSE). In the term "memory-efficient" SSE, we encompass both the goals of local SSE, and page-efficient SSE. The centerpiece of our approach is a novel connection between those two goals.

CoD-DSSE: A practical efficient dynamic searchable symmetric encryption with lightweight clients

Journal of King Saud University: Computer and Information Sciences
Dynamic searchable symmetric encryption(DSSE) combines dynamic update with searchable encryption, allowing users to not only achieve keyword retrieval, but also dynamically update encrypted data stored on semi-trusted cloud server, effectively protecting

A privacy-preserving cloud storage framework with hybrid encryption, homomorphic keyword search, and blockchain-based integrity verification [PDF]

Scientific Reports
Cloud storage outsourcing introduces critical privacy risks as Cloud Service Providers (CSPs) can access unencrypted user data, while encryption eliminates essential functionality such as searchability and remote integrity verification.

Dynamic Searchable Symmetric Encryption with Physical Deletion and Small Leakage

, 2017
Dynamic Searchable Symmetric Encryption (DSSE) allows a client not only to search over ciphertexts as the traditional searchable symmetric encryption does, but also to update these ciphertexts according to requirements, e.g., adding or deleting some ciphertexts. It has been recognized as a fundamental and promising method to build secure cloud storage.
