Setup-Free Secure Search on Encrypted Data: Faster and Post-Processing Free

Secure Conjunctive Keyword Search over Encrypted Data

We study the setting in which a user stores encrypted documents (e.g. e-mails) on an untrusted server. In order to retrieve documents satisfying a certain search criterion, the user gives the server a capability that allows the server to identify exactly those documents. Work in this area has largely focused on search criteria consisting of a single keyword. If the user is actually interested i...

Secure Multi-keyword Similarity Search Over Encrypted Cloud Data Supporting Efficient Multi-user Setup

Searchable encryption allows one to store encrypted documents on a remote honest-butcurious server, and query that data at the server itself without requiring the documents to be decrypted prior to searching. This not only protects the data from the prying eyes of the server, but can also reduce the communication overhead between the server and the user and local processing at the latter. Previ...

A Unified Framework for Secure Search Over Encrypted Cloud Data

This paper presents a unified framework that supports different types of privacy-preserving search queries over encrypted cloud data. In the framework, users can perform any of the multi-keyword search, range search and k-nearest neighbor search operations in a privacypreserving manner. All three types of queries are transformed into predicate-based search leveraging bucketization, locality sen...

Secure keyword-based Ranked Semantic Search over Encrypted Cloud Data

With the advent of cloud computing, many organizations and individuals are interested in outsourcing their complex data management to the public cloud for economic savings and ease of access. As sensitive information may have to be encrypted before outsourcing, the data utilization service based on plaintext keyword search is not suitable for the encrypted cloud data. In this paper, we propose ...
