A Rankable Boolean Searchable Encryption Scheme Supporting Dynamic Updates in a Cloud Environment

Searchable Encryption Supporting General Boolean Expression Queries

BSSE algorithms  Each keyword is considered as a vector in order to perform inner product during the search phase.  Boolean symmetric searchable encryption BSSE is mainly based on the orthogonalization of the keyword field according to the GramSchmidt process.  Searchable encryption: Searching encrypted keywords using encrypted queries (trapdoor) in order to retrieve encrypted documents with...

Implementing a Similarity Searchable Encryption Scheme for Cloud Database Usage

SESOS: A Verifiable Searchable Outsourcing Scheme for Ordered Structured Data in Cloud Computing

While cloud computing is growing at a remarkable speed, privacy issues are far from being solved. One way to diminish privacy concerns is to store data on the cloud in encrypted form. However, encryption often hinders useful computation cloud services. A theoretical approach is to employ the so-called fully homomorphic encryption, yet the overhead is so high that it is not considered a viable s...

Searchable Encryption in Cloud Storage

Cloud outsource storage is one of important services in cloud computing. Cloud users upload data to cloud servers to reduce the cost of managing data and maintaining hardware and software. To ensure data confidentiality, users can encrypt their files before uploading them to a cloud system. However, retrieving the target file from the encrypted files exactly is difficult for cloud server. This ...

An Efficient Symmetric Searchable Encryption Scheme for Cloud Storage

Symmetric searchable encryption for cloud storage enables users to retrieve the documents they want in a privacy-preserving way, which has become a hotspot of research. In this paper, we propose an efficient keyword search scheme over encrypted cloud data. We firstly adopt a structure named as inverted matrix (IM) to build search index. The IM is consisted of index vectors, each of which is ass...
