Detailed Quantum Cryptographic Service and Data Security in Cloud Computing

This paper presents a holistic security solution for cloud computing environment by proposed a new secured cloud framework, which known as cryptographic cloud computing environment (CCCE) [14, 15]. CCCE entails both a trusted cloud-user and an innovative quantum cryptographic service (QCaaS). QCaaS is a new security service that responsible to solve the key generation, key distribution and key management problems, which emerged through the negotiation between the communications parties (cloud-user and cloud provider). Such service includes a proposed symmetric quantum encryption algorithm that is explained in previous work, usually called quantum advanced encryption standard (QAES). QAES build by the integration between a quantum key distribution (QKD) and an enhanced version of AES using two different modes, On-line and Off-line mode. Additionally, CCCE implemented using the system center manager 2012-SPI, which in turn, installed and configured based bare-metal Hyper-V, it poses more secured data transmission channels by provisioning secret key among cloud’s instances. Finally, CCCE reveals a higher secure data transmission comparing to other cloud security systems especially in key generation, key management, defeating almost type of attacks, and the impact rate of the proposed solution on the performance of cloud resources.
