A Fog-Centric Quantum Security for Cloud Storage Scheme with Enhanced Multipath Routing Architecture

Abstract

Now a days the cloud computing has been widely used in day to day life. Confidentiality, Integrity, and Availability are basic goals of security architecture. To ensure CIA, many authentication scheme has been introduced in several years. Every type of data is stored in the cloud and it can be easily accessed at any time and any place. But, while coming to the privacy in the cloud computing it steps behind due to location awareness. Cloud computing uses a fog-centric secure scheme to protect data against unauthorized access, modification, and destruction. To prevent the illegitimate access, the scheme employs a new technique Xor-Combination to conceal data. Moreover, Block-Management outsources the outcomes of Xor-Combination to prevent malicious retrieval and to ensure better recoverability in case of data loss. The current system uses hash algorithm for detection with higher probability.  But the current algorithm does not providing better efficiency and security. The Proposed work is a different approach when compare with existing system for securing data in the cloud using segment technology and faster multipath routing. Proposed approach will be providing the better efficiency and security for the cloud storage. To enhance the efficiency of fog based cloud storage service, multi path file transmission has been used, in which a file will be divided into many parts and transmit to cloud servers via various fog servers. Currently deployment of Public Key Infrastructure (PKI) is a most significant solution. PKI involving exchange key using certificates via a public channel to a authenticate users in the cloud infrastructure. However, there is a certain issue pertaining to the PKI authentication where the public key cryptography only provide computational security because PKI is based on Asymmetric Key Cryptography. It is exposed to widespread security threats such as eavesdropping, man in the middle attack, masquerade et al. This paper aims to look into basic security architecture in place currently and further it tries to introduce a new proposed security architecture, which makes use of the knowledge of Quantum Mechanics and current advances in research in Quantum Computing, to provide a more secure architecture.
