Tight Tradeoffs in Searchable Symmetric Encryption
Journal of Cryptology, 2018 A searchable symmetric encryption (SSE) scheme enables a client to store data on an untrusted server while supporting keyword searches in a secure manner. Recent experiments have indicated that the practical relevance of such schemes heavily relies on the tradeoff between their space overhead, locality (the number of non-contiguous memory locations ...

Research on asymmetric searchable encryption [PDF]
AIP Conference Proceedings, 2017 Cloud server side to ease the user’s local storage pressure at the same time, there are hidden data on the hidden dangers, the user often choose to upload the data in the form of cipher text to the cloud server. However, the classic data encryption and decryption algorithms are not provided search function, affecting the user’s efficiency. To this end,

Towards Blockchain-Enabled Searchable Encryption [PDF]
, 2020 Distributed Leger Technologies (DLTs), most notably Blockchain technologies, bring decentralised platforms that eliminate a single trusted third party and avoid the notorious single point of failure vulnerability. Since Nakamoto's Bitcoin cryptocurrency system, an enormous number of decentralised applications have been proposed on top of these ...

Towards Multi-user Searchable Encryption Supporting Boolean Query and Fast Decryption [PDF]
Journal of Universal Computer Science, 2019 Searchable encryption enables the data owner to outsource their data to the cloud server while retaining the search ability. Recently, some researchers proposed a variant of searchable encryption, named single-writer/multi-reader searchable encryption ...

Generating Searchable Public-Key Ciphertexts with Hidden Structures for Fast Keyword Search [PDF]
IEEE Transactions on Information Forensics and Security, Vol. 10,
no. 9, pp. 1993-2006, 2015, 2015 Existing semantically secure public-key searchable encryption schemes take search time linear with the total number of the ciphertexts. This makes retrieval from large-scale databases prohibitive. To alleviate this problem, this paper proposes Searchable Public-Key Ciphertexts with Hidden Structures (SPCHS) for keyword search as fast as possible ...
