Universally Composable Forward Secure Dynamic Searchable Symmetric Encryption

Proceedings of the 8th ACM on ASIA Public-Key Cryptography Workshop, 2021
Kurosawa et al. formulate a universally composable (UC) security definition of dynamic searchable symmetric encryption (DSSE). They also show (weak) equivalence between the UC and the game-based definition, and introduce a UC secure DSSE scheme (KSOY scheme).

Dynamic Symmetric Searchable Encryption from Constrained Functional Encryption

2016
Searchable symmetric encryption allows a party to encrypt data while maintaining the ability to partially search for over it. We present a scheme that balances efficiency, privacy, and the set of admissible operations: Our scheme searches in time logarithmic in the size of the word dictionary i.e., it is independent of the number of files, satisfies ...

UC-Secure Dynamic Searchable Symmetric Encryption Scheme

2016
In a dynamic searchable symmetric encryption (SSE) scheme, a client can add/modify/delete encrypted files. In this paper, we first prove a weak equivalence between the UC security and the stand alone security based on the previous work on static SSE schemes.

Multi-User Dynamic Searchable Symmetric Encryption With Corrupted Participants.

IEEE Trans. Dependable Secur. Comput., 2022
We study the problem of multi-user dynamic searchable symmetric encryption (DMUSSE) where a data owner stores its encrypted documents on an untrusted remote server and wishes to selectively allow multiple users to access them by issuing keyword search queries.

Forward-Private Dynamic Searchable Symmetric Encryption with Efficient Search

2018 IEEE International Conference on Communications (ICC), 2018
Dynamic Searchable Symmetric Encryption (DSSE) allows to delegate keyword search and file update over an encrypted database via encrypted indexes, and therefore provides opportunities to mitigate the data privacy and utilization dilemma in cloud storage platforms. Despite its merits, recent works have shown that efficient DSSE schemes are vulnerable to

Keyword-Search Interval-Query Dynamic Symmetric Searchable Encryption

2019
Searchable Symmetric Encryption (SSE) enables clients to securely store data on untrusted server while keeping the ability to search and update over the encrypted data efficiently. For practical purposes, we also need several additional properties to make our search function more versatile.

Multi-user Forward Secure Dynamic Searchable Symmetric Encryption

2018
Searchable Symmetric Encryption (SSE) makes it possible to privacy-preserving search over encrypted data stored on an untrusted server. Dynamic SSE schemes add the ability for the user to support secure update of encrypted data records. However, recent attacks show that update information can be exploited to recover the underlying values of ciphertexts.

Dynamic Searchable Symmetric Encryption with Forward and Backward Privacy: A Survey

2019
Searchable symmetric encryption (SSE) has been proposed that enables the clients to outsource their private encrypted data onto the cloud server and later the data can be searched with limited information leakage. However, existing surveys have not covered most recent advances on SSE technique.

Dynamic searchable symmetric encryption

2016
The subject of this thesis is "Dynamic Searchable Symmetric Encryption" (DSSE). DSSE is one of the solutions that can be used for implementations of searchable encryption schemes. Searchable encryption allows a client to outsource the storage of its encrypted data to a server, while maintaining the ability to search over the data without downloading it.
