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.

Dynamic Multi-Phrase Ranked Search over Encrypted Data with Symmetric Searchable Encryption

IEEE Transactions on Services Computing, 2020
As cloud computing becomes prevalent, more and more data owners are likely to outsource their data to a cloud server. However, to ensure privacy, the data should be encrypted before outsourcing. Symmetric searchable encryption allows users to retrieve keyword over encrypted data without decrypting the data.

Conjunctive Keyword Forward Secure Ranked Dynamic Searchable Encryption Over Outsourced Encrypted Data

2021
Cloud Computing enables individuals and organizations with extensive computing capabilities along with scalable storage services. However the security of outsourced data brings about privacy concerns when confidential data is outsourced to third party service providers.

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 ...

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.

Privacy-Preserving Searchable Encryption Scheme over Encrypted Data Supporting Dynamic Update

2019
With the advancement of network technology, cloud computing services have become popular due to the on-demand availability of computing resources, large-scale data storage and distribution. Many users are influenced to outsource their private data to cloud servers to cut the costs of building by storing their data locally.

Benchmarking Dynamic Searchable Symmetric Encryption with Search Pattern Hiding

2019 International Conference on Intelligent Computing and its Emerging Applications (ICEA), 2019
Searchable symmetric encryption (SSE) is an important technique for cloud computing. SSE allows encrypted critical data stored on an untrusted cloud server to be searched using keywords, returning correct data, but the keywords and data content are unknown by the server. However, an SSE database is not practical because the data is generally frequently

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.

Forward Privacy Analysis of a Dynamic Searchable Encryption Scheme

2020
Dynamic searchable encryption is one branch of searchable encryption. Compared with the static searchable encryption, a dynamic searchable encryption scheme can support update (add or delete) of outsourced data. However, this kind of operation may cause data leakage.
