Searchable Symmetric Encryption

ACM Computing Surveys, 2017
Searchable Symmetric Encryption (SSE) when deployed in the cloud allows one to query encrypted data without the risk of data leakage. Despite the widespread interest, existing surveys do not examine in detail how SSE’s underlying structures are designed and how these result in the many properties of a SSE scheme.

Symmetric Searchable Encryption with Sharing and Unsharing [PDF]

, 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 [PDF]

, 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.

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 ...

Multi-level Access in Searchable Symmetric Encryption [PDF]

, 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.

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.

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.

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.
