Enhancement of security and privacy in mobile data centers is challengeable with efficient security key management. In order to solve this problem, data centers need efficient quantum cryptography using Grover's algorithm and authentication technique which are appropriate approaches to enhance the security and privacy with less complexity. In this research, quantum cryptography with the PairHand protocol seems to be a better approach. In future, light which has same quantum properties will be the best approach because people can see only the light not the data. So, light based on quantum cryptography and PairHand protocols will be the best for this research.

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.
A quantum cryptography security model in mobile cloud computing is proposed in this paper, so as to achieve highly-secure data and privacy cryptography in mobile cloud computing environment. In the model, quantum keys are distributed to users' phones through two phases. Firstly, existing classical optical network has been transformed as quantum distribution network conveniently through multiplexing technique, the BB84 quantum key distribution protocol realized based on decoy state is adopted; Then, the security authentication protocol based on the quantum keys and distance-bounding HKQ is put forward, and through the near field communication (NFC) technology, quantum keys are transmitted into the security storage area of users' phone in the trusted area; Mobile users can get access to data on the cloud through quantum secret keys, protecting users' data and privacy. Experiments in the real quantum cryptography environment prove the validity of the proposed QCMC model.
The advent of quantum computing threatens to undermine current encryption methods significantly, especially those employed in mobile data transmission networks. Quantum algorithms can solve the computational challenges behind present public-key encryption methods like RSA (Rivest-Shamir-Adleman) and elliptic curve cryptography at a speedy rate. With mobile communication networks handling more and more sensitive information, the availability of secure authentication methods is increasingly important. This project proposes to investigate how mobile data communication systems can leverage post-quantum cryptographic (PQC) techniques to enhance authentication protocols. The research compares some NIST-standardized post-quantum cryptography candidates, i.e., lattice-based, code-based, hash-based, and multivariate polynomial cryptography, focusing on their usage in mobile environments. We establish a guideline for constructing PQC-improved authentication protocols, focusing on their quantum-resistance, computational cost, and appropriateness for resource-constrained mobile devices. Our analysis proves that the regulations successfully protect information’s secrecy, integrity, and authenticity in the post-quantum era. This has led to the development of future-proof, safe, and resilient mobile communication networks. PQC augmented authentication systems offer good resistance against quantum attacks while supporting acceptable performance on mobile devices, as evidenced by previous research. Mobile communication systems can achieve long-term security through PQC, thus safeguarding user data and critical infrastructure against potential adversaries that might employ quantum computing in the future.
Modern cryptography targeted towards providing data confidentiality still pose some limitations.The security of public-key cryptography is based on unproven assumptions associated with the hardness /complicatedness of certain mathematical problems.However, public-key cryptography is not unconditionally secure: there is no proof that the problems on which it is based are intractable or even that their complexity is not polynomial.Therefore, public-key cryptography is not immune to unexpectedly strong computational power or better cryptanalysis techniques.The strength of modern cryptography is being weakened and with advances of big data, could gradually be suppressed.Moreover, most of the currently used public-key cryptographic schemes could be cracked in polynomial time with a quantum computer.This paper presents a renewed focus in fortifying the confidentiality of big data by proposing a quantum-cryptographic protocol.A framework was constructed for realizing the protocol, considering some characteristics of big data and conceptualized using defined propositions and theorems.
Security knowledge is one of the foremost challenges in the present day. When the topic is about Information security, the concept of cryptography comes into the picture. Every day, people and organizations use cryptography to maintain the confidentiality of their communications and data as well as to preserve their privacy. Today, one of the most successful methods used by businesses to protect their storage systems, whether at rest or in transit, is cryptography. Yet, cryptography is an effective technique to secure the data, the modern technology can break the cryptographic techniques. But some data encryption algorithms are several times stronger than today's conventional cryptography and can be constructed using quantum computing. They are "Quantum Cryptographic Algorithms ". Quantum cryptography uses the rules of quantum physics instead of classical encryption, which is based on mathematics, to protect and transmit data in a way that cannot be intercepted. Quantum key distribution is the greatest illustration of quantum cryptography and offers a safe solution to the key exchange issue. The proposed work deals with quantum cryptography and mainly focuses on how the quantum cryptographic algorithm is more secure than traditional cryptography.
