A Novel Scheme for Data Security in Cloud Computing using Quantum Cryptography

Cloud computing manifests exceptional capacity to facilitate easy to manage, cost effective, flexible and powerful resources across the internet. Due to maximum and shared utilization of utilization of resources, cloud computing enhances the capabilities of resources. There is a dire need for data security in the wake of the increasing capabilities of attackers and high magnitude of sensitive data. Cryptography is employed to ensure secrecy and authentication of data. Conventional information assurance methods are facing increasing technological advances such as radical developments in mathematics, potential to perform big computations and the prospects of wide-ranging quantum computations. Quantum cryptography is a promising solution towards absolute security in cryptosystems. This paper proposes integration of Advanced Encryption Standard (AES) algorithm with quantum cryptography. The proposed scheme is robust and meets essential security requirements. The simulation results show that the Quantum AES produces complex keys which are hard to predict by adversaries than the keys generated by the AES itself.
