CloudQKDP: Quantum key distribution protocol for cloud computing
G. Murali, R. Sivaram Prasad · 2016
A novel computing paradigm, the cloud computing, has become a viable solution on top of virtualization for commoditization of computing resources. Though it has potential to leverage individuals and organizations with plethora of advantages, there are strong security concerns over outsourced data. The existing security models are built with certain assumptions. The solutions like distributed accountability, provable data possession (PDP), Third Party Auditing (TPA) and so on are secure as long as the assumptions hold true. To ensure fool proof security for cloud storage security little research has been made on quantum key cryptography. Since the quantum key distribution is unconditionally secure we propose a new scheme known as CloudQKDP (Quantum Key Distribution Protocol for Cloud Computing) which exploits the benefits of quantum mechanisms to secure cloud storage and data dynamics. We consider a case study in which three parties such as cloud server, data owner and trusted client have provably secure communications with our proposed scheme which uses random oracle model. Our empirical study revealed mixture of success and failure rates with private and public clouds respectively.
