Abstract

The central remote servers are essential for storing and processing data for cloud computing evaluation. However, traditional systems need to improve their ability to provide technical data security solutions. Many data security challenges and complexities await technical solutions in today's fast-growing technology. These complexities will not be resolved by combining all secure encryption techniques. Quantum computing efficiently evolves composite algorithms, allowing for natural advances in cyber security, forensics, artificial intelligence, and machine learning-based complex systems. It also demonstrates solutions to many challenging problems in cloud computing security. This study proposes a user-storage-transit-server authentication process model based on secure keys data distribution and mathematical post-quantum cryptography methodology. The post-quantum cryptography mathematical algorithm is used in this study to involve the quantum computing-based distribution of security keys. It provides security scenarios and technical options for securing data in transit, storage, user, and server modes. Post-quantum cryptography has defined and included the mathematical algorithm in generating the distributed security key and the data in transit, on-storage, and on-editing. It has involved reversible computations on many different numbers by super positioning the qubits to provide quantum services and other product-based cloud-online access used to process the end-user's artificial intelligence-based hardware service components. This study will help researchers and industry experts prepare specific scenarios for synchronizing data with medicine, finance, engineering, and banking cloud servers. The proposed methodology is implemented with single-tenant, multi-tenant, and cloud-tenant-level servers and a database server. This model is designed for four enterprises with 245 users, and it employs integration parity rules that are implemented using salting techniques. The experimental scenario considers the plain text size ranging from 24 to 8248 for analyzing secure key data distribution, key generation, encryption, and decryption time variations. The key generation and encryption time variations are 2.3233 ms to 8.7277 ms at quantum-level 1 and 0.0355 ms to 1.8491 ms at quantum-level 2. The key generation and decryption time variations are 2.1533 ms to 19.4799 ms at quantum-level 1 and 0.0525 ms to 3.3513 ms at quantum-level 2.

M. Thangapandiyan, P. M. Rubesh Anand, K. Sakthidasan Sankaran

Providing security to the Personal Health Record (PHR) stored in cloud is an important and critical task in recent days. Different cloud security mechanisms are developed in the traditional works for this purpose mainly focused on authentication based security. This paper aims to develop a novel key distribution and encryption mechanism namely, Quantum Key Distribution and Non-Abelian Encryption (QKD-NAE) for secure storage and access of PHR. In cloud environment, the hospital admin and user uses a quantum key for data access, where the users may be a doctor, patient, nurse, physicians, and accountants. The hospital admin uses the Diffie Hellman (DH) algorithm for secure secret generation, and every user separates the secret based on their designation. Then, the admin splits the input data into attributes and encrypts it by using NAE. When the user sends the request to the service provider, the access control policy maintained by the Third Party Auditor (TPA) is verified for data access. The valid user receives the data from multiple servers based on the access control policy created by the DH algorithm. The major advantage of this work is that the unauthorized users are not able to know the quantum key and the generated secret which leads to increased data security. The experimental results evaluate the performance of the existing and proposed techniques with respect to different measures.

Enhancing cloud data security using quantum key distribution (QKD) and quantum cryptography

Sarjiyus, Umaru Adamu, Salamatu

Cloud computing systems face serious security risks that are intensified by advances in quantum computing because powerful quantum algorithms such as Shor's algorithm can break widely used public-key schemes which include RSA and ECC. The cloud environment needs Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD) as countermeasures but their individual deployment creates problems because scalability and infrastructure requirements become obstacles for multi-tenant systems. This research proposes a hybrid security architecture that uses both hardware-based QKD for symmetric key generation over optical fibers and PQC for authentication through quantum-resistant key encapsulation using CRYSTALS-Kyber and digital signatures with CRYSTALS-Dilithium. The hybrid design uses XOR to combine the QKD-generated secret with the PQC-derived key material which creates the final session key yet security remains intact if either component gets compromised. The system tested on a private cloud testbed with 10 virtual machines and a 50 km commercial QKD link through optical fiber measured performance against Classical TLS 1.3 and PQC-TLS and QKD-only configurations. The results showed that QKD-only achieved the lowest handshake latency of 5.2 ms while the hybrid approach delivered the strongest security through a 19.8 ms overhead which was only 1.7 ms slower than pure PQC. After creating the secure channel all systems achieved similar data throughput of about 942 Mbps which shows that quantum-security mechanisms affect the connection setup phase instead of persistent data transfer.

We analyze the shift from classical security models to quantum-resistant frameworks, evaluating the trade-offs between computational efficiency, key management, and implementation scalability in multi-tenant cloud environments. Furthermore, we explore advanced protocols such as Quantum Secure Direct Communication, quantum coin tossing, and oblivious transfer, which offer novel methods for privacy-preserving computation. By addressing the current implementation challenges and the necessity for international standardization, this study outlines a strategic roadmap for integrating quantum-resilient mechanisms to ensure the long-term confidentiality and integrity of cloud-based data against both classical and quantum adversaries. Keywords: Quantum Computing, Post-Quantum Cryptography (PQC), Cloud Security 1.Introduction As quantum threats become more imminent, assessing and comparing quantum-based protocols is essential for strengthening cloud security frameworks. Potential quantum-enabled adversaries leveraging advanced computational capabilities to compromise sensitive information. Therefore, a thorough comparison of existing quantum-safe protocols, including lattice-based, code-based, and multivariate cryptography, is critical for determining the most effective strategies to secure cloud environments. potential quantum attacks by leveraging cryptographic methods that remain secure even in the presence of powerful quantum adversaries. 2.Quantum Computing Foundations Recent advancements in quantum computing have prompted researchers and organizations to reevaluate traditional cryptographic techniques within cloud security infrastructures. Cloud environments are particularly susceptible to attacks such as data breaches, insider threats, and man-in-the-middle intrusions due to their distributed and multi-tenant nature. As a result, integrating quantum-resistant algorithms and protocols is increasingly regarded as a necessary step to mitigate emerging vulnerabilities in cloud-based systems. This heightened vulnerability necessitates the exploration of robust quantum security protocols designed to mitigate risks unique to cloud-based systems. These protocols aim to safeguard data transmission and user authentication against adversaries equipped with quantum computing capabilities. Consequently, the development and adoption of quantum security measures is becoming an essential priority for maintaining the confidentiality and integrity of sensitive information in cloud environments. 3.Cloud Security Concepts and Vulnerabilities In addition to enhancing data confidentiality and authentication, these protocols also support advanced cryptographic operations such as oblivious transfer, paving the way for more secure and privacy-preserving cloud services. Furthermore, quantum security protocols facilitate new methods for secure computation and collaboration among distributed cloud users without exposing sensitive underlying data. As cloud services continue to evolve, integrating quantum security protocols is expected to become a foundational aspect of next-generation cloud infrastructure. 4.Overview of Quantum Security Protocols These advancements are particularly crucial as traditional cryptographic techniques face growing risks from quantum computing breakthroughs, necessitating proactive adaptation in cloud security frameworks. Quantum key distribution (QKD) is among the most prominent quantum security protocols, enabling the establishment of secure encryption keys between cloud entities using fundamental principles of quantum mechanics. This protocol ensures that any eavesdropping attempt can be detected due to the inherent properties of quantum measurements, thereby greatly enhancing cloud communication security. QKD has already seen early-stage experimental deployment in cloud environments, demonstrating potential for secure key exchange between data centers and distributed cloud nodes. As research progresses, QKD is being integrated with existing cloud infrastructure to explore scalable and efficient implementations that can accommodate the dynamic nature of cloud services. These integration efforts aim to address challenges such as network scalability, cost-efficiency, and interoperability with classical cryptographic systems. Additionally, ongoing studies focus on the seamless orchestration of QKD-enabled services with cloud management platforms to facilitate practical adoption. Furthermore, collaboration between academia and industry is accelerating the development of standardized QKD protocols and integration frameworks tailored for multi-tenant cloud environments. 5.Quantum Key Distribution in Cloud Environments Such standardization efforts are expected to promote widespread interoperability and lay the groundwork for commercially viable quantum-secured cloud services. These advancements contribute to a growing ecosystem where quantum-secured communication can become an integral part of mainstream cloud infrastructure. In parallel, research into Quantum Secure Direct Communication, quantum coin tossing, and other advanced quantum protocols is broadening the security landscape for cloud applications. Quantum Secure Direct Communication offers a method for transmitting confidential information directly over quantum channels without relying on shared encryption keys. This emerging technology is being explored for applications ranging from secure message delivery to safeguarding critical cloud operations against quantum attacks. As such, it holds promise for enabling real-time, tamper-resistant communication and may complement or even replace traditional secure key exchange mechanisms in certain cloud scenarios. Ongoing investigations also include quantum coin tossing and oblivious transfer, which aim to enable secure two-party computations and fair decision-making without trusting a single party. These protocols are progressively shaping the future of secure cloud services by addressing novel threats posed by quantum computing capabilities. 6.Quantum Secure Direct Communication This section delves deeper into the principles, implementation methods, and evolving use cases of quantum coin tossing and oblivious transfer within the context of quantum-secure cloud communication. Quantum coin tossing enables two remote parties to generate a random outcome in a way that neither can cheat or bias the result, even in the presence of advanced quantum adversaries. Oblivious transfer, on the other hand, allows a sender to transfer one of potentially many pieces of information to a receiver, where the sender remains oblivious to which piece was chosen, enhancing privacy in quantum-secure protocols. Together, these protocols form foundational building blocks for constructing more complex, privacy-preserving functionalities critical to secure quantum cloud environments. Their integration into cloud environments promises to strengthen the overall resilience of distributed computing architectures against both classical and quantum threats. As advances in quantum algorithms continue to threaten classical cryptographic schemes, there is growing urgency to explore and adopt post-quantum cryptography alternatives for securing cloud-based communications. These advances necessitate ongoing research and collaborative efforts to ensure robust, scalable, and future-proof security measures for cloud platforms in the quantum era. Adopting these novel protocols will require not only technological innovation but also the development of new standards, interoperability frameworks, and policy guidelines tailored to the evolving quantum landscape. Furthermore, educating stakeholders and fostering awareness about post-quantum security implications will play a crucial role in facilitating smooth adoption and compliance across industries. In addition, cross-disciplinary initiatives involving academia, industry, and government will be essential to accelerate the transition toward quantum-resilient cloud infrastructures. Such partnerships can drive the creation of shared testbeds, encourage best practices, and support continuous evaluation of emerging quantum security solutions. The synergy between these sectors is expected to enable more robust integration of quantum-safe mechanisms, ensuring that cloud services remain secure and adaptable as quantum technologies mature. 6.1.Quantum Coin Tossing and Oblivious Transfer Collaborative research efforts will also help identify gaps in current protocols and inspire innovative approaches to integrating quantum-resistant techniques within complex cloud environments. These collaborative initiatives will also facilitate the early adoption of post-quantum cryptographic alternatives, ensuring cloud infrastructures remain resilient against evolving threats. Furthermore, ongoing industry-academic-government collaborations will be crucial for standardizing post-quantum cryptography alternatives, promoting interoperability, and accelerating widespread deployment in the cloud. 7.Post-Quantum Cryptography Alternatives Such alternatives include lattice-based, hash-based, code-based, and multivariate schemes, each offering varying levels of security and implementation complexity suitable for diverse cloud applications. As cloud providers evaluate these schemes, considerations such as computational efficiency, scalability, and ease of integration will play a pivotal role in determining which alternatives are most viable for practical deployment.
