UC-Secure Searchable Symmetric Encryption

2012
For searchable symmetric encryption schemes (or symmetric-key encryption with keyword search), the security against passive adversaries (i.e. privacy) has been mainly considered so far. In this paper, we first define its security against active adversaries (i.e. reliability as well as privacy). We next formulate its UC-security.

Symmetric Searchable Encryption with Sharing and Unsharing

2018
In this paper, we study Symmetric Searchable Encryption (SSE) in a multi-user setting in which each user dynamically shares its documents with selected other users, allowing sharees also to perform searches. We introduce the concept of a Symmetric Searchable Encryption with Sharing and Unsharing, an extension of Multi-Key Searchable Encryption (NSDI ...

Memory leakage-resilient searchable symmetric encryption

Future Generation Computer Systems, 2016
Along with the popularization and rapid development of cloud-computing, more and more individuals and enterprises choose to store their data in cloud servers. However, in order to protect data privacy and deter illegal accesses, the data owner has to encrypt his data before outsourcing it to the cloud server.

Practical Backward-Secure Searchable Encryption from Symmetric Puncturable Encryption

Proceedings of the 2018 ACM SIGSAC Conference on Computer and Communications Security, 2018
Symmetric Searchable Encryption (SSE) has received wide attention due to its practical application in searching on encrypted data. Beyond search, data addition and deletion are also supported in dynamic SSE schemes. Unfortunately, these update operations leak some information of updated data.

Garbled Searchable Symmetric Encryption

2014
In a searchable symmetric encryption (SSE) scheme, a client can keyword search over symmetrically-encrypted files which he stored on the server (ideally without leaking any information to the server). In this paper, we show the first multiple keyword search SSE scheme such that even the search formula \(f\) (AND, OR and so on) is kept secret.

Verifiable Searchable Symmetric Encryption from Indistinguishability Obfuscation

Proceedings of the 10th ACM Symposium on Information, Computer and Communications Security, 2015
Searchable symmetric encryption (SSE) allows a client to encrypt his data in such a manner that the data can be efficiently searched. SSE has practical application in cloud storage, where a client outsources his encrypted data to a cloud server while maintaining the searchable ability over his data. Most of the current SSE schemes assume that the cloud

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.

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.

Parallel and Dynamic Searchable Symmetric Encryption

2013
Searchable symmetric encryption (SSE) enables a client to outsource a collection of encrypted documents in the cloud and retain the ability to perform keyword searches without revealing information about the contents of the documents and queries. Although efficient SSE constructions are known, previous solutions are highly sequential.
