Multi-Client Searchable Symmetric Encryption in Redactable Blockchain for Conjunctive Queries

International Symposium on Computers and Communications, 2023
Sharing and searching encrypted data securely in outsourced environments poses a challenge due to possible cooperation between compromised users and untrusted servers. This paper studies the problem of multi-client dynamic searchable symmetric encryption,

Improved Indistinguishability for Searchable Symmetric Encryption

2020
This work presents a new experiment defining indistinguishability for searchable symmetric encryption to include security against published practical attacks. The proposed experiment allows the adversaries to use their prior knowledge about the stored documents to win.

Forward Private Verifiable Dynamic Searchable Symmetric Encryption With Efficient Conjunctive Query

IEEE Transactions on Dependable and Secure Computing
Dynamic searchable symmetric encryption (DSSE) allows efficient searches over encrypted databases and also supports clients in their updating of the data, such as those stored in a remote cloud server.

Volume-Hiding Range Searchable Symmetric Encryption for Large-Scale Datasets

IEEE Transactions on Dependable and Secure Computing
Searchable Symmetric Encryption (SSE) is a valuable cryptographic tool that allows a client to retrieve its outsourced data from an untrusted server via keyword search.

UC-Secure Searchable Symmetric Encryption

2012
For searchable symmetric encryption schemes (or symmetric-key encryption with keyword search), the security against passive adversaries (i.e. privacy) has been mainly considered so far. In this paper, we first define its security against active adversaries (i.e. reliability as well as privacy). We next formulate its UC-security.

Symmetric Searchable Encryption with Sharing and Unsharing

2018
In this paper, we study Symmetric Searchable Encryption (SSE) in a multi-user setting in which each user dynamically shares its documents with selected other users, allowing sharees also to perform searches. We introduce the concept of a Symmetric Searchable Encryption with Sharing and Unsharing, an extension of Multi-Key Searchable Encryption (NSDI ...

Memory leakage-resilient searchable symmetric encryption

Future Generation Computer Systems, 2016
Along with the popularization and rapid development of cloud-computing, more and more individuals and enterprises choose to store their data in cloud servers. However, in order to protect data privacy and deter illegal accesses, the data owner has to encrypt his data before outsourcing it to the cloud server.

Themis: Robust and Light-Client Dynamic Searchable Symmetric Encryption

IEEE Transactions on Information Forensics and Security
Dynamic searchable symmetric encryption (DSSE), as one of the promising cryptographic tools in cloud-based services, faces two crying needs at the age of multi-device. One is a lightweight client, and the other is robustness.
