Empowering users of cloud computing on data confidentiality

Abstract

Cloud networking is an integral part of interconnected data centres operated in cloud environment. Cloud users heavily rely on cloud networking to transmit to and receive data from data centres. In this context, we explore how to provide cloud users with more controls so that they could ensure confidentiality of their data without using extensive public key encryption in cloud networking or sharing secret keys. We propose an approach for secure transmission of matrix multiplication over cloud networking using randomisation, column-row shuffling and size alteration of matrices. The main philosophy of this approach is to equip cloud users with more controls of ensuring confidentiality of their data without using any additional overhead computation. In this approach, the cloud users hold the entire secret values, without sharing with or depending on other parties for secret key generation, sharing and storing.
