چکیده

This paper presents a new range query mechanism to query encrypted databases that reside at third-party, untrusted, servers. This paper is a continuation of work done by others [1]; our scheme seeks to improve the precision of querying encrypted data sets, increase the utilization of server side processing and reduce the computation and memory utilization on the client side. We compare our algorithm with previous work, and quantify the performance improvements using numerical results.

Private Key based query on encrypted data

Nowadays, users of information systems have inclination to use a central server to decrease data transferring and maintenance costs. Since such a system is not so trustworthy, users' data usually upkeeps encrypted. However, encryption is not a nostrum for security problems and cannot guarantee the data security. In other words, there are some techniques that can endanger security of encrypted d...

Design and Analysis of Querying Encrypted Data in Relational Databases

Security and privacy concerns as well as legal considerations force many companies to encrypt the sensitive data in databases. However, storing the data in an encrypted format entails non-negligible performance penalties while processing queries. In this paper, we address several design issues related to querying encrypted data in relational databases. Based on our experiments, we propose new a...

Anti-Tamper Databases: Querying Encrypted Databases

With mobile computing and powerful laptops, databases with sensitive data can be physically retrieved by malicious users who can employ techniques that were not previously thought of, such as disk scans, compromising the data by bypassing the database management system software or database user authentication processes. Or, when databases are provided as a service, the service providers may not...

Measuring Inference Exposure in Outsourced Encrypted Databases

Database outsourcing is becoming increasingly popular introducing a new paradigm, called database-as-a-service, where an encrypted client’s database is stored at an external service provider. Existing proposals for querying encrypted databases are based on the association, with each encrypted tuple, of additional indexing information obtained from the plaintext values of attributes that can be ...

A Processing Model for the Optimal Querying of Encrypted XML Documents in XQuery

XQuery is a powerful and convenient language that is designed for querying the data in XML documents. In this paper, we address how to optimally query encrypted XML documents using XQuery, with the key point being how to eliminate redundant decryption so as to accelerate the querying. We propose a processing model that can automatically and appropriately translate the XQuery statements for encr...
