Verifiable Multilevel Dynamic Searchable Encryption With Forward and Backward Privacy in Cloud-Assisted IoT

IEEE Internet of Things Journal
The Internet of Things (IoT) boom has enabled massive data collection in cloud servers. Therefore, access efficiency and data privacy in cloud storage services have become a significant concern.

Verifiable memory leakage-resilient dynamic searchable encryption

Journal of High Speed Networks, 2018
Searchable symmetric encryption (SSE) allows a data owner to outsource his encrypted data to a cloud server while retaining the ability to perform keyword search over encrypted data. The security guarantees of existing SSE schemes require that the adversary has no access to the data owner’s secret keys. Unfortunately, adversaries may get some or all of

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).

CFB-DSSE: Efficient Secure Dynamic Searchable Encryption Scheme with Conjunctive Search for Smart Healthcare

International Conference on Trust, Security and Privacy in Computing and Communications
Smart healthcare provides more convenient services to patients and medical institutions. However, it also suffers from medical data privacy leakage and broad query results.

$\mathsf {SENTRY}$: A Compliance-Check Service for Dynamic Searchable Encryption With Sanitized Authorization Query

IEEE Transactions on Services Computing
Searchable encryption enables privacy-preserving queries over data outsourced to cloud services. Classical symmetric schemes deliver efficient search but largely assume a single-client setting; multi-client variants permit delegation yet typically treat ...

Optimization-Based Statistical Query Recovery Attack on Dynamic Searchable Encryption

2026 9th International Conference on Computer Information Science and Application Technology (CISAT)
Dynamic Searchable Encryption (DSE) schemes typically tolerate some predefined leakages (e.g., volume patterns of query response and response file) during runtime to balance efficiency and security.

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.
