Searchable encryption for geo-referenced data

2016 Mediterranean Ad Hoc Networking Workshop (Med-Hoc-Net), 2016
Searchable encryption schemes allow to query on encrypted data in a secure way. In this work we present different techniques that achieve range queries in searchable encryption, thus enhancing performance and reducing the leakage of information. We focus on the case of one and two-dimensional range queries to an encrypted geo-referenced database in a ...

A Blockchain-Based Anonymous Attribute-Based Searchable Encryption Scheme for Data Sharing

IEEE Internet of Things Journal
Attribute-based searchable encryption (ABSE) is a promising encryption mechanism for sharing outsourced encrypted data in clouds, allowing fine-grained access control over data while searching for encrypted data.

Searchable Public-Key Encryption With Cryptographic Reverse Firewalls for Cloud Storage

IEEE Transactions on Cloud Computing, 2023
In order to protect data privacy in cloud storage, sensitive data is encrypted before being uploaded to a cloud server. How to retrieve ciphertext safely and effectively has become a problem.

A Format-compatible Searchable Encryption Scheme for JPEG Images Using Bag-of-words

ACM Trans. Multim. Comput. Commun. Appl., 2022
The development of cloud computing attracts enterprises and individuals to outsource their data, such as images, to the cloud server. However, direct outsourcing causes the extensive concern of privacy leakage, as images often contain rich sensitive ...

Device-Oriented Keyword-Searchable Encryption Scheme for Cloud-Assisted Industrial IoT

IEEE Internet of Things Journal, 2022
Massive physical devices are deployed in the Industrial Internet of Things (IoT) to collect ambiance data while heavy storage and communication cost are imposed on these IoT devices. To overcome this constraint, cloud-assisted technologies are introduced

Attribute-Based Symmetric Searchable Encryption

2020
Symmetric Searchable Encryption (SSE) is an encryption technique that allows users to search directly on their outsourced encrypted data while preserving the privacy of both the files and the queries. Unfortunately, majority of the SSE schemes allows users to either decrypt the whole ciphertext or nothing at all.

Secure Channel Free Certificate-Based Searchable Encryption Withstanding Outside and Inside Keyword Guessing Attacks

IEEE Transactions on Services Computing, 2021
Searchable public key encryption (SPKE) is a useful public key cryptographic primitive that allows a user to perform keyword searches over publicly encrypted messages on an untrusted storage server while guaranteeing the privacy of the original messages ...

KeySea: Keyword-Based Search With Receiver Anonymity in Attribute-Based Searchable Encryption

IEEE Transactions on Services Computing, 2022
In modern digital age, enterprise applications typically outsource user data in pubic cloud storage with the objective of availing flexibility and scalability features of cloud infrastructure, and importantly, making business goal more cost effective ...

Decryptable Searchable Encryption

2007
As such, public-key encryption with keyword search (a.k.a PEKS or searchable encryption) does not allow the recipient to decrypt keywords i.e. encryption is not invertible. This paper introduces searchable encryption schemes which enable decryption. An additional feature is that the decryption key and the trapdoor derivation key are totally independent,

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.
