Publisher

Abstract

The paper proposes a new data encryption scheme for cloud computing that uses quantum cryptography to improve security. The titles are also different in terms of their length, tone, and focus. For example, the title "Quantum-enhanced AES for Cloud Computing Security" is the most concise and straightforward title, while the title "A Novel Quantum-secure Data Encryption Scheme for Cloud Computing" is more descriptive and informative. The title "Quantum-safe Data Protection in Cloud Computing" is more concise and to the point, while the title "Securing Cloud Data with Quantum AES" is more focused on the specific encryption scheme that is proposed. Ultimately, the best title for the paper will depend on the specific goals of the author and the intended audience. If the author is primarily interested in communicating the technical details of the proposed scheme, then a more concise and informative title would be appropriate. If the author is more interested in communicating the general benefits of quantum cryptography for cloud computing, then a more descriptive and engaging title would be better.

Geeta Sharma, Sheetal Kalra

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.

Quantum-Enhanced Security Advances for Cloud Computing Environments

Devulapally Swetha, Shaik Khaja Mohiddin

Recent developments in quantum-enhanced security have demonstrated encouraging promise for enhancing cloud computing environments' security. Utilizing quantum physics, in particular Quantum Key Distribution (QKD), provides a new method for generating cryptographic keys and improves cloud data transport security. The present study offers a thorough investigation of the integration of QKD with conventional encryption techniques, including Advanced Encryption Standard (AES), in order to tackle the dynamic cyber security scenario in cloud computing. The approach entails combining AES for encryption and decryption procedures and establishing a QKD layer within the cloud architecture to produce true quantum keys utilizing Quantum in Cloud technology. Data transmission security is greatly improved by the smooth integration of AES with QKD-generated keys, guaranteeing confidentiality, integrity, and authenticity. In addition, strong key management practices are put in place to handle cryptographic keys safely at every stage of their lifespan, reducing the possibility of unwanted access or interception. The suggested approach successfully addresses the difficulties presented by cyber threats by offering a robust and flexible means of enhancing security in cloud-based systems. Using both traditional and quantum encryption methods, this strategy provides a strong barrier against cyber-attacks, data leaks, and other security flaws. After 70 simulation rounds, the suggested strategy, which is implemented using the QKD-AES framework in Python software, achieved a data access rate of 820 MB/s. In addition to providing an accurate and quantitative assessment of the performance, this also exhibits a high data access rate attained under simulated conditions. At 15 milliseconds, the key generation time was achieved with efficiency, guaranteeing the quick creation of secure cryptographic keys in cloud environments. Overall, there is a lot of potential in using quantum-enhanced security techniques to protect sensitive data and guarantee the integrity of cloud computing infrastructures.
