Multi-level Access in Searchable Symmetric Encryption

2017
Remote storage delivers a cost effective solution for data storage. If data is of a sensitive nature, it should be encrypted prior to outsourcing to ensure confidentiality; however, searching then becomes challenging. Searchable encryption is a well-studied solution to this problem.

Multi-client Cloud-based Symmetric Searchable Encryption

IEEE Transactions on Dependable and Secure Computing, 2019
We propose a multi-client Symmetric Searchable Encryption (SSE) scheme based on the single-user protocol [3] . The scheme allows any user to generate a search query by interacting with any $\theta -1$ θ - 1 ( $\theta$ θ is a threshold parameter) ‘helping’ users.

Efficient No-dictionary Verifiable Searchable Symmetric Encryption

2017
In the model of no-dictionary verifiable searchable symmetric encryption (SSE) scheme, a client does not need to keep the set of keywords \(\mathcal{W}\) in the search phase, where \(\mathcal{W}\) is called a dictionary. Still a malicious server cannot cheat the client by saying that “your search word w does not exist in the dictionary \(\mathcal{W}\)”

Ranked Searchable Symmetric Encryption Supporting Conjunctive Queries

2017
Searchable symmetric encryption allows searching over the encrypted data directly without decryption, which is particularly useful in cloud computing as users can outsource the data to cloud servers without privacy leakage while retaining the ability to search.

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 ...

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.
