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].
Enhancement of security in cloud computing is challengeable when big data such as medical and government confidential information involves in a cloud environment.The managing key for individual user participated in the mobile cloud will be the problem when big data is handled without efficient security key management.Especially, mobile cloud nodes where users handle their data can be anywhere else in the cloud environment.So, managing keys for random users and finding correct locations of users" nodes and their identities are interesting areas for the research.To solve this problem related to key management, cloud services need efficient key management that employs quantum cryptography using Grover"s algorithm.Moreover, in this research, we introduce effective authentication technique in order to improve the level of security (with minimum complexity) In this paper, theoretical model, Grover"s algorithm and quantum cryptography with the PairHand protocol are considered as methodologies.As summarized results, security levels of users and services providers are considered to verify the services used in a cloud environment.In spite of same quantum properties characterize the light, data security issues are still not matured with the light technology.Hiding the big data in the light through this research methodology will be the conclusion of the future security.
A governmental and business organizations employ handheld devices like palmtops and smart cellular phones for communication, collaboration, and purchases, the problem of privacy and security arise. Essential encryption systems present themselves as a problem to the current nature of mobility since most of the previous encryption methods evolved with the centralized systems. Quantum cryptography can thus be regarded as a perfect solution to the above challenges given the fact that it employs principles of quantum mechanics such as quantum key distribution (QKD) to secure communications in mobile platforms. This paper aims at examining the use of quantum cryptography in mobile computing systems whereby an endeavor is made to determine how quantum communication algorithms can be incorporated into the current mobile communication standards. The efficiency of the quantum cryptography is also discussed in the context of protection from threats that are characteristic for the mobile networks, such as wiretapping and data theft. Also, we touch on such issues as how practical, easily scalable, and suitable for mobile systems quantum cryptography is in terms of computational and network burden. Thus, in this paper, the author would like to show that by applying quantum cryptography, end-to-end privacy can be effectively achieved in the field of mobile computing and explain its significance for the development of next generations of mobile security.
Quantum cryptographic protocols offer transformative potential for enhancing cloud security by leveraging the principles of quantum mechanics. These protocols ensure unbreakable encryption through quantum key distribution (QKD), where security is derived from the fundamental properties of quantum particles. Unlike classical encryption, which relies on computational complexity, quantum cryptography guarantees data protection by preventing unauthorized access, as any attempt to intercept quantum keys alters their state and can be immediately detected. This paper explores the application of quantum cryptographic protocols in securing cloud environments, addressing vulnerabilities posed by classical encryption techniques in the face of growing computational power. Key protocols, such as BB84 and E91, are analyzed for their potential in securing cloud infrastructure, offering enhanced confidentiality, integrity, and authentication of data. Additionally, this study highlights the integration of quantum cryptography with modern cloud architectures, overcoming challenges such as scalability and implementation cost. By employing quantum-resistant strategies, these protocols provide a robust defense against emerging threats from quantum computing, making them an essential solution for future-proof cloud security. The findings demonstrate that quantum cryptography, combined with advanced cloud security practices, can ensure secure, scalable, and resilient cloud infrastructures capable of protecting sensitive data in an increasingly interconnected digital landscape.
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.
With the growing adoption of cloud computing, ensuring data security in cloud environments has become a critical concern for business organizations. Quantum cryptography utilizes the principles of quantum mechanics to guarantee secure communication, as any attempt to eavesdrop will change the quantum states, alerting the parties of the intrusion. This paper proposes a multi-qubit Quantum Key Distribution (QKD) ciphertext-policy attribute-based encryption (CP-ABE) for cloud security. The proposed multi-qubit QKD model for secure cloud data using quantum cryptography involves the use of a quantum key distribution protocol to generate a secure key for encryption and decryption. This protocol involves sending quantum signals through a quantum channel to distribute a secret key between the sender and the receiver. The key is then used for the encryption and decryption of data using the CP-ABE technique. This technique allows the encryption and decryption of data based on attributes rather than an explicit key exchange, making it particularly suitable for cloud environments where data is stored and processed by multiple users with varying levels of access. The positive results from the proposed simulation model suggest the potential of quantum cryptography in securing cloud data.
