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

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 ...

Attribute-Based Symmetric Searchable Encryption

2020
Symmetric Searchable Encryption (SSE) is an encryption technique that allows users to search directly on their outsourced encrypted data while preserving the privacy of both the files and the queries. Unfortunately, majority of the SSE schemes allows users to either decrypt the whole ciphertext or nothing at all.

Computationally Efficient Searchable Symmetric Encryption

2010
Searchable encryption is a technique that allows a client to store documents on a server in encrypted form. Stored documents can be retrieved selectively while revealing as little information as possible to the server. In the symmetric searchable encryption domain, the storage and the retrieval are performed by the same client.

Toward Practical Searchable Symmetric Encryption

2013
Searchable symmetric encryption is a good building block toward ensuring privacy preserving keyword searches in a cloud computing environment. This area has recently attracted a great deal of attention and a large quantity of research has been conducted.

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.

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.
