Fuzzy Multi-Keyword Search for Multi-Owner Scenario in IoV

IEEE Transactions on Vehicular Technology
As the Internet of Vehicles (IoV) continues to evolve, data owners consistently upload private information to the nearest roadside unit (RSU), which may pose significant risks of privacy leakage.

Privacy-Preserving Multi-Keyword Search in Information Networks

IEEE Transactions on Knowledge and Data Engineering, 2015
In emerging information networks, it is crucially important to provide efficient search on distributed documents while preserving their owners’ privacy, for which privacy preserving indexes or PPI presents a possible solution. An understudied problem for the PPI techniques is how to provide differentiated privacy preservation in the presence of multi-

Multi-keyword Search Based on Attribute Encryption

2019
To address the problems of key leakage and large computation amount in current attribute-based searchable encryption (SE) schemes, this study proposes a multi-keywords ranked search scheme based on attribute encryption in cloud environment. Firstly, the scheme not only supports fine-grained search authorisation, but also has constant ciphertext length.

Efficient Secure Text Retrieval on Multi-Keyword Search

Proceedings of the Eighth International Symposium on Information and Communication Technology, 2017
It is necessary to protect the data, while the data owner still let the users retrieve the information. In this paper, we present a secure text retrieval on multi keyword search, where the data owners and users can guarantee the privacy of their documents and searching keywords against the semi-trusted document servers while maintaining the ...

Threshold Multi-Keyword Search for Cloud-Based Group Data Sharing

IEEE Transactions on Cloud Computing, 2020
Searchable Encryption (SE) is a popular cryptographic primitive for building ciphertexts retrieval systems with far-reaching applications. However, existing SE schemes generally do not support threshold access control (i.e., data users must ...

Key-Escrow Free Attribute-Based Multi-Keyword Search with Dynamic Policy Update in Cloud Computing

IEEE/ACM International Symposium on Cluster, Cloud and Internet Computing, 2020
Attribute-based searchable encryption (ABSE) schemes provide searchability and fine-grained access control over encrypted data in the cloud. Although prior ABSE schemes are designed to provide data protection and retrieval efficiency, they are suffering ...

Public Key Encryption with Multi-keyword Search

2012
Since the notion of Public-Key Encryption with Keyword Search (PEKS) scheme was proposed, many revisions and extensions have been given. Public-Key Encryption with Multi-Keyword Search(PEMKS) is one of these extensions, which means that the receiver could query subset keywords of all the keywords embedded in the ciphertext.

Fast Multi-Keyword Range Search Using GPGPU

2014
Large organisations are constantly challenged by the need to handle big data. Big data sizes are a constantly moving target, as of 2013 ranging from a few dozen terabytes to many petabytes of data. The data is usually stored in very large databases that are often indexed off-line to enable the acceleration of on-line searches.

Multi Keyword Search on Encrypted Text Without Decryption

2020
Various organizations use plain text to store data related to day-to-day computations. Data is stored in the form of plain text documents without any structure and specifications. Retrieval and searching from structured data will be easier with various existing database systems. Querying and searching on unstructured content is difficult.

Approximate Multi-Keyword Rank Search on Encrypted Cloud Data

GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017
With the growing popularity of cloud computing, more and more data owners outsource their data to cloud storages because of the convenience for management. Since cloud storages are usually run by third party service providers, data security is definitely an important problem.
