Blockchain-based searchable symmetric encryption scheme

Computers & 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 ...

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.

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.

Dynamic searchable symmetric encryption

Proceedings of the 2012 ACM conference on Computer and communications security, 2012
Searchable symmetric encryption (SSE) allows a client to encrypt its data in such a way that this data can still be searched. The most immediate application of SSE is to cloud storage, where it enables a client to securely outsource its data to an untrusted cloud provider without sacrificing the ability to search over it.SSE has been the focus of ...

Boolean symmetric searchable encryption

Proceedings of the 8th ACM SIGSAC symposium on Information, computer and communications security, 2013
In this article we tackle the issue of searchable encryption with a generalized query model. Departing from many previous works that focused on queries consisting of a single keyword, we consider the the case of queries consisting of arbitrary boolean expressions on keywords, that is to say conjunctions and disjunctions of keywords and their complement.
