An Effective Data Security Mechanism for Secured Data Communications Using Hybrid Cryptographic Technique and Quantum Key Distribution

One of the most flamboyant technological novelties of today's world is cloud computing, which has been fuelled by the increase in the number of smart devices across the internet. With the continuous advancement in the technical field, cloud computing has played a significant role in enabling the user to share, store and retrieve data from anywhere at any time. The involvement of many users in cloud computing, questions the security of the data present on the cloud. Existing features in cloud security are vulnerable to potential risks including lack of confidentiality, integrity, and authentication. In this paper, we propose a new data security mechanism using newly proposed hybrid encryption system (HES) and quantum key distribution (QKD) for secured data communication in cloud networks. The newly proposed HES uses the standard cryptographic algorithms namely AES and RSA for performing effective encryption and decryption processes. The newly proposed QKD is ensured the secured data communications by generating and distributing the reliable keys to the authorized users. Moreover, the novelty is introduced in the suggested model ensures reliable distribution of keys among the users and in turn preserves the data through secure hybrid encryption. At the end, the scrutiny of the proposed system proves that it is preferable that the existing models in terms of secure communication, reliability and performance.
