Distributed Searchable Symmetric Encryption [PDF]
, 2014 Searchable Symmetric Encryption (SSE) allows a client to store encrypted data on a storage provider in such a way, that the client is able to search and retrieve the data selectively without the storage provider learning the contents of the data or the ...

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

HardIDX: Practical and Secure Index with SGX [PDF]
, 2017 Software-based approaches for search over encrypted data are still either challenged by lack of proper, low-leakage encryption or slow performance. Existing hardware-based approaches do not scale well due to hardware limitations and software designs that

Forward-secure hierarchical predicate encryption [PDF]
, 2012 Secrecy of decryption keys is an important pre-requisite for security of any encryption scheme and compromised private keys must be immediately replaced. \emph{Forward Security (FS)}, introduced to Public Key Encryption (PKE) by Canetti, Halevi, and Katz

Forward and Backward Private Searchable Encryption from Constrained Cryptographic Primitives [PDF]
, 2017 Using dynamic Searchable Symmetric Encryption, a user with limited storage resources can securely outsource a database to an untrusted server, in such a way that the database can still be searched and updated efficiently.

Forward Secure Conjunctive-Keyword Searchable Encryption
IEEE 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 ...
