Blockchain-Based Employment Contract System Architecture Allowing Encrypted Keyword Searches

Privacy Preserving Keyword Searches on Remote Encrypted Data

We consider the following problem: a user U wants to store his files in an encrypted form on a remote file server S. Later the user U wants to efficiently retrieve some of the encrypted files containing (or indexed by) specific keywords, keeping the keywords themselves secret and not jeopardizing the security of the remotely stored files. For example, a user may want to store old e-mail message...

Foreseer: A Novel, Locality-Aware Peer-to-Peer System Architecture for Keyword Searches

Peer-to-peer (P2P) systems are becoming increasingly popular and complex, serving millions of users today. However, the design of current unstructured P2P systems does not take full advantage of rich locality properties present in P2P system workloads, thus possibly resulting in inefficient searches or poor system scalability. In this paper, we propose a novel locality-aware P2P system architec...

A Survey on Keyword Based Search over Outsourced Encrypted Data

To ensure security, encryption techniques play a major role when data are outsourced to the cloud. Problem of retrieving the data from the cloud servers is considered. Many searching techniques are used for retrieving the data. This study focused on a set of keyword based search algorithms. It provides secure data retrieval with high efficiency. It concludes Ranked Searchable Symmetric Encrypti...

Threshold Privacy Preserving Keyword Searches

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 ...
