Cloud computing have become the budding engine of current information technology (IT) as a result of the rapid development of IT, security protection has become more and more important for cloud computing. The theft of identity authentication in sequence remains a serious hazard to the protection of cloud computing, in this process, attackers infringe into cloud computing services through identity certification information, thereby threatening the security of data from multiple perspectives. Most types of attack can cause the classified information be in the hand of unauthorized party. This situation will lead to data disclosure and the user feel insecure for using the services offered by cloud infrastructure. In this work a novel protocol is proposed to secured cloud authentication using quantum cryptography.

Nowadays, Information Technology group is undergone significant shift in computing and protecting business value by using well-built, workable and authentic replacement of Cloud Computing.Cloud Computing is a contemporary computational architecture that provides another type of model.Cloud Computing provides substantial measure of computing, storage services, Data classification, IT assets and data management and cyber security.An unauthorized user may be accessed this data through virtual machines.This uncertainty creates a big problem.Cloud Computing is used in both public and private sector due to its accessibility, availability, and cost effectiveness.However, security of data transfer between client and server is still a big problem.Many scientists and researchers have brought up another cryptographic subject in Quantum Computing which is called Quantum Key Distribution (QKD).The first QKD protocol is BB84 that was presented by Charles Bennett and Gilles Brassard in 1984 [4].This paper proposes as a service of Advanced Quantum Cryptography in Cloud Computing.This paper discusses the security issues of cloud computing and the role of cryptography technique in Cloud computing to enrich the Information Security [13].
The rise of cloud computing has transformed data storage and processing but introduced new vulnerabilities, especially with the impending threat of quantum computing. Traditional cryptographic methods, though currently effective, are at risk of being compromised by quantum attacks. This research aims to develop a quantum-resistant security framework for cloud environments, combining lattice-based cryptography with Quantum Key Distribution (QKD) protocols, particularly the E91 protocol, for secure key management. The framework also incorporates quantum authentication protocols to enhance user identity verification, protecting against unauthorized access and tampering. The proposed solution balances robust security with practical implementation, ensuring scalability and efficiency in real-world cloud environments. Performance evaluations indicate an encryption time of approximately 30 milliseconds, outperforming existing methods such as RSA and DES. This research contributes to the development of future-proof cryptographic standards, addressing both current security challenges and emerging quantum computing threats. By leveraging quantum mechanics, the framework strengthens cloud-based data protection, providing a resilient solution against evolving cyber risks. The results hold significant promise for advancing cloud security, laying the groundwork for next-generation encryption techniques that can withstand the threats posed by quantum computing.
Confidentiality, Integrity, and Availability are basic goals of security architecture. To ensure CIA, many authentication scheme has been introduced in several years. Currently deployment of Public Key Infrastructure (PKI) is a most significant solution. PKI involving exchange key using certificates via a public channel to a authenticate users in the cloud infrastructure. It is exposed to widespread security threats such as eavesdropping, the man in the middle attack, masquerade et al. Quantum cryptography is of the most prominent fields in the modern world of information security. Quantum cryptography is considered to be a future replica of classical cryptography along with a vital stance to break existing classical cryptography. This paper aims to look into basic security architecture in place currently and further it tries to introduce a new proposed security architecture for cloud computing environment, which makes use of the knowledge of Quantum Mechanics and current advances in research in Quantum Computing, to provide a more secure architecture.
The widespread cryptographic methods RSA and AES have become more susceptible to quantum-based attacks because researchers developed quantum algorithms such as Shor's and Grover's. QKD chromosomes from quantum mechanics grant authorized parties the ability to exchange cryptographic keys securely alongside built-in eavesdropping detection functionality. In the proposed method a Quantum Key Distribution (QKD) is used to integrate into cloud environments to secure data against quantum threats which have become crucial security concerns today. A new security framework for combining QKD with standard cloud utilities strengthens both access privacy and verify data integrity and ensure authentication of user information. The system framework consists of key generation from quantum elements followed by distribution through quantum channels to support secure communication protocols for Software as a Service (SaaS) and Platform as a Service (PaaS) as well as Infrastructure as a Service (IaaS). The key performance evaluation of the QKD system includes measurements of key generation rate together with Quantum Bit Error Rate (QBER) and eavesdropping detection accuracy rates. The analysis against traditional cryptographic systems proves that QKD stands superior in quantum attack resilience. The proposed system demonstrates its efficiency and robustness through simulation outcomes as well as visual representations. The presented work demonstrates both the revolutionary capability of quantum technology for cloud security along with a deployable system architecture for future systems implementation. The research work advances the creation of cloud infrastructure systems which combine high security resilience to protect against future cyber threats.
Cloud computing offer the cost-effective and flexibility to the user. However, the security threat is a main concern for user to place their data in the cloud. Data that stored and shares through cloud have to be confidential and restricted. Information leakage, men in the middle attack are the two main issues that make information stored in the cloud insecure. Widely authentication method used is the classical approach like Public Key Infrastructure (PKI). This approach is workable in order to provide a secure environment within the cloud clients. The existing of Certificate Authority that act as controller they can verify the legal user. However, in certain circumstances, this approach cannot solve the issue such as stealing the identity. In this paper we are proposing a model that use quantum mechanical theory. This theory is supporting the no cloning theory. It used the power of light and a single photon to provide an authentication key. Throughout this paper, we also do a literature on various security threats, and authentication method in cloud. Then, we are introducing a quantum defense model as a solution of the listed threats. We proposed new cloud authentication architecture for cloud computing environment. A new cloud authentication environment that implements quantum mechanics is proven that can gain more trust with less time of computation in cloud communications.
Abstract: As cloud computing becomes a central part of everyday operations, securing these environments against growing cyber threats is increasingly critical. Traditional security measures are struggling to keep pace with the rapid development of new attack methods, particularly as quantum computing threatens to break existing encryption standards. This paper explores the integration of blockchain and quantum cryptography to address these challenges and strengthen cloud security. While blockchain offers a visible, unchangeable record that guarantees data integrity, quantum cryptography offers encryption methods that are resistant to assaults based on quantum mechanics, safeguarding transactions and communications. When combined, these technologies offer a hybrid security strategy that defends cloud systems against potential quantum computing vulnerabilities while simultaneously combating current cyberattacks. The essay also examines how this hybrid approach may assist in the creation of a more secure and resilient cloud infrastructure in the future, as well as the practical challenges of implementing this integrated strategy, such as scalability and computational efficiency.
