Searchable symmetric encryption: Improved definitions and efficient constructions [PDF]

Journal of Computer Security, 2006
Searchable symmetric encryption (SSE) allows a party to outsource the storage of his data to another party in a private manner, while maintaining the ability to selectively search over it. This problem has been the focus of active research and several security definitions and constructions have been proposed.

Blockchain-based searchable symmetric encryption scheme

Computers and Electrical Engineering, 2019
Abstract The mechanism for traditional searchable symmetric encryption (SSE) is pay-then-use. This situation is not fair to user because the cloud server may return wrong results. Besides, the user needs to verify these results locally. In order to ensure fairness and reduce user’s calculations, we combined blockchain with SSE, and proposed a fair ...

Forward secure searchable symmetric encryption

2017 12th International Conference for Internet Technology and Secured Transactions (ICITST), 2017
Data outsourcing to third party clouds poses numerous data security threats. Access by unauthorized users is one of the security threat to the outsourced data. Unauthorized access can be avoided by encrypting the data before outsourcing. However, encrypting data before outsourcing renders it unsearchable to the data owner. Searchable encryption schemes

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.

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.

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.

Symmetric Searchable Encryption for Database Applications

2011 14th International Conference on Network-Based Information Systems, 2011
This paper proposes an efficient symmetric searchable encryption to achieve indistinguishability of indexes and trapdoors. Previous symmetric searchable encryptions are either insecure because their trapdoor generation algorithms are not probabilistic or inefficient because of the heavy cost due to pairing-based computation.

A Mechanized Proof of Security for Searchable Symmetric Encryption

2015 IEEE 28th Computer Security Foundations Symposium, 2015
We present a mechanized proof of security for an efficient Searchable Symmetric Encryption (SSE) scheme completed in the Foundational Cryptography Framework (FCF). FCF is a Coq library for reasoning about cryptographic schemes in the computational model that features a small trusted computing base and an extensible design.

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.
