Quantum computing has emerged as a transformative technology with the potential to revolutionize various domains, including cryptography. This research paper addresses the pressing issue of enhancing cryptographic protocols in cloud security through the integration of quantum computing. The main objective of this study is to develop and evaluate novel cryptographic protocols that leverage the computational power of quantum systems to enhance security measures in cloud environments.To achieve this objective, we employed a hybrid methodology that combines classical cryptographic techniques with quantum algorithms. Specifically, we designed a framework incorporating quantum key distribution (QKD) and post-quantum cryptographic (PQC) algorithms to ensure robust security against quantum attacks. The framework was implemented and tested in a simulated cloud environment to assess its effectiveness and performance.The results indicate that the proposed quantum-enhanced cryptographic protocols significantly improve the security and resilience of cloud systems. Our findings demonstrate that the integration of QKD and PQC provides a higher level of security compared to traditional cryptographic methods, effectively mitigating potential threats posed by quantum computers. Additionally, the performance analysis shows that the proposed protocols are computationally feasible and can be integrated into existing cloud infrastructures with minimal overhead.In conclusion, this research highlights the potential of quantum computing to address critical security challenges in cloud computing. The proposed quantum-enhanced cryptographic protocols offer a promising solution for protecting sensitive data in cloud environments against emerging quantum threats. Future work will focus on refining these protocols and exploring their practical applications in real-world cloud systems. .
Abstract Quantum computing (QC) is an emerging area that yearly improves and develops more advances in the number of qubits and the available infrastructure for public users. Nowadays, the main cloud service providers (CSP) are implementing different mechanisms to support access to their quantum computers, which can be used to perform small experiments, test hybrid algorithms and prove quantum theories. Recent research work have discussed the low capacity of using quantum computers in a single CSP to perform quantum computation that are needed to solve different experiments for real world problems. Thus, there are needs for computing powers in the form of qubits from multi-cloud environment. Quantum computing in a multi-cloud environment requires security of the communicating channels. A well known algorithm in quantum cryptography for this purpose is the quantum key distribution (QKD) protocol. This enables the sender and receiver of a message to know when a third party eavesdropped any data from the insecure quantum channel. To address the low capacity issue, this research develops and tests the use of heterogeneous quantum computers located on different CSP to distribute quantum calculations between them by leveraging the channel security provided by the QKD protocol. The achieved results show over 88.1% of correct distributed quantum computation results without error correction methods, 96.8% of correct distributed quantum computation results using error correction methods and over 98.8% correct authorisation detection in multi-cloud environments. This demonstrates that quantum calculations can be distributed between different CSP while securing the channel with the QKD protocol at the same time.
This paper presents a novel protocol for secure multi-party computation (MPC) within a quantum network, integrating Quantum Key Distribution (QKD) and quantum state secure computation techniques. The core objective is to enable multiple parties to collaboratively perform computations without revealing their individual inputs. The proposed protocol establishes a secure communication channel using QKD, guaranteeing the exchange of secret keys. Subsequently, a quantum state secure multi-party computation algorithm is employed, ensuring the confidentiality and integrity of the computation process. The utilization of quantum key distribution significantly enhances the security of the entire system, mitigating vulnerabilities associated with traditional MPC schemes. The theoretical analysis demonstrates the protocol's resilience against various attacks, providing a foundation for building robust and secure quantum network applications. The protocol's effectiveness hinges on the ability to maintain quantum coherence during the computational steps and accurately manage the quantum key distribution process. This research contributes to the advancement of secure quantum computing and communication technologies.
Abstract Security and privacy have always been key concerns for individuals in various cloud-assisted services. In order to enhance security, we focus on quantum cryptography in novel cloud-based applications. First, we present two quantum primitive protocols to compute XOR of two private bits and AND of two private bits with the assistance of a quantum cloud, respectively. Then, we generalize two-party protocols to the corresponding multi-party cases. These quantum primitive protocols can ensure information-theoretical security and provide long-term security, which are guaranteed by the principles of quantum mechanics. Furthermore, we present a grouping strategy to improve the communication efficiency of multiparty quantum protocols. In addition, we investigate privacy-preserving applications of these quantum primitive protocols in cloud-based environments, e.g., cloud-based Anonymous Voting and Multiparty Private Set Intersection. Finally, simulated experiments show our proposed quantum protocols are correct and feasible with the present quantum technology.
This research is introducing an enhanced tight finite key scheme for quantum key distribution (QKD) protocol to authenticate multi-party system in cloud infrastructure. The main attraction is to provide a secure channel between a cloud client to establish a connection among them by applying the theories from Von Neumann and Shannon entropies and also Shor's algorithm. By generalizing these theories we will produce enhanced tight finite key scheme for quantum key distribution (QKD) protocol to authenticate multi-party system in cloud infrastructure. Hence we are using quantum channel and also quantum key distribution (QKD) together with BB84 protocol replacing common channel to distribute the key. We are proposing an authentication of multi-party Quantum Key Distribution (MQKD) protocol using an enhanced tight finite key scheme because it will involve a number of parties in cloud infrastructure. Significant of this research is to reduce the possibility of losing a private key by producing a high efficient key rate and attack resilient.
The integration of quantum computing into multi-cloud environments represents a transformative paradigm in distributed computing, offering substantial improvements in computational efficiency, security resilience, and adaptive workload orchestration. However, the heterogeneous nature of cloud infrastructures, combined with the nascent and resource-sensitive characteristics of quantum systems, introduces significant architectural, operational, and security challenges. This paper proposes an optimized quantum computing integration approach designed specifically for multi-cloud ecosystems, emphasizing scalable architecture design, intelligent workload distribution, and enhanced cryptographic security mechanisms.The study synthesizes foundational quantum computing principles with contemporary multi-cloud orchestration strategies to develop a hybrid architectural framework. The proposed model leverages quantum-enhanced optimization techniques, including quantum approximate optimization principles, to dynamically allocate computational tasks across distributed cloud nodes. Additionally, it integrates quantum-safe security protocols to mitigate emerging cyber threats in cloud environments. Prior research highlights the relevance of such integration, particularly in solving complex optimization problems and enhancing system-level security (Brown & White, 2022; Cao et al., 2020).A structured literature synthesis reveals that while cloud computing and quantum computing have individually matured, their convergence remains underexplored in practical deployment contexts. This paper addresses this gap by introducing an architecture that supports adaptive workload balancing, quantum-classical hybrid execution layers, and secure inter-cloud communication channels. The findings indicate that quantum-enhanced orchestration can significantly reduce computational latency and improve resource utilization efficiency in multi-cloud systems.
