Hardware Acceleration of Searchable Encryption

Proceedings of the 2018 ACM SIGSAC Conference on Computer and Communications Security, 2018
Searchable symmetric encryption (SSE) allows a client to outsource the storage of her data to an (untrusted) server in a private manner, while maintaining the ability to selectively search over it. A key feature of all existing SSE schemes is the tradeoff between security (in terms of the information leakage to the server) and efficiency (in terms of ...

Unconditionally secure searchable encryption

2017 51st Annual Conference on Information Sciences and Systems (CISS), 2017
Searchable symmetric encryption (SSE) enables us to search encrypted data with an arbitrarily chosen keyword without leaking information on the data and keyword. SSE is expected to be used in, for example, cloud computing and genome analyses. In particular, privacy of genome data must be guaranteed for long periods, and therefore unconditionally secure

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.

Cloud Architectures for Searchable Encryption

Proceedings of the 13th International Conference on Availability, Reliability and Security, 2018
Blomer et al. have presented a cloud architecture for enabling fine-grained cryptographic access control to data in the cloud. The architecture is intended to provide this service to large-scale orgnaizations. We revisit the cloud architecture, and enrich it with searchable encryption.

Lightweight Verification for Searchable Encryption

2018 17th IEEE International Conference On Trust, Security And Privacy In Computing And Communications/ 12th IEEE International Conference On Big Data Science And Engineering (TrustCom/BigDataSE), 2018
Symmetric Searchable Encryption (SSE) is a promising primitive to securely perform keyword queries and to efficiently retrieve associated files from a curious server without sacrificing data privacy. Unfortunately, besides being curious, an untrusted server could also be malicious, which would return incorrect or incomplete results to a client. Since a

Broadcast Searchable Keyword Encryption

2014 IEEE 17th International Conference on Computational Science and Engineering, 2014
Broadcast Searchable Keywords Encryption (BSKE) is a novel scheme that allows searching in encrypted data without knowing a secret key. Consider Bob wants to encrypt the same data under master public key for a group of users and stores this encrypted data with Alice, Malice is one of those recipients he asks Alice using his private key whether or not ...

Searchable Encryption in Apache Cassandra

2016
In today’s cloud computing applications it is common practice for clients to outsource their data to cloud storage providers. That data may contain sensitive information, which the client wishes to protect against this untrustworthy environment. Confidentiality can be preserved by the use of encryption.

Error-Tolerant Searchable Encryption

2009 IEEE International Conference on Communications, 2009
In this paper, we describe a new primitive for Error-Tolerant Searchable Encryption and a security model for it. This generic scheme permits to make searches on encrypted data with only an approximation of some keyword. It enables to efficiently query secure databases in order to get the exact data with a close estimation of it.

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.
