Cloud computing is a rapid growing technology which delivers computing services such as servers, storage, database, networking, software and analytics. It has brought a new way to securely store and share information and data with multiple users. When authorized person access these clouds, the released data should not compromise any individual’s privacy and identity should not be revealed. Fog Computing is the extension of cloud with decentralized structure which stores the data in locations somewhere between the data source and cloud. The goal of fog computing is to provide high security, improve performance and network efficiency. We use quantum key distribution to produce and distribute key which change its quantum state and key, when key is known by mediator and it has ability to detect presence of mediator trying to gain lore of the key. In this paper, we introduced sugar-salt encryption which overcomes brute-force attack in effect delivers phony data in return to every incorrect guess of the password or key.

Cloud computing is swiftly developing, delivering a diverse spectrum of computing utilities like databases, storage, and servers. It transfigures the way data storage is done and securely circulated among numerous users. Nevertheless, enabling privacy and restricting identity breaches when availing cloud utilities is essential. Fog Computing, an updated version of the cloud framework, utilizes a decentralized architecture to maintain data between the cloud and the data sources. This procedure seeks to improve performance, network connectivity, and most importantly provide security. Quantum key distribution (QKD) is employed in fog computing architectures to develop and circulate keys. The employed keys change their quantum configurations, enabling them to be highly safe. Further, an intermediary maintaining the key can identify any endeavor by illegal entities to operate it. In this research article, we utilize sugar-salt encryption, an approach designed to oppose brute-force invasions efficiently. This encryption procedure delivers erroneous data in reply to wrong password/key insertions, improving data protection, which is pivotal in online based banking data protection.
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.
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].
As technology advances, it becomes easier to share large amounts of data over the internet. Cloud computing is one of the technologies that allows for easy data sharing over the internet. It is critical to provide security for this data when they are being shared across the internet. The security of data saved in cloud storage, as well as data transport and transmitting a key required to encrypt data between two parties, has been a source of concern for the industry, as a result of the growing use of cloud services in recent years. Collective attacks are significantly more powerful than individual strikes, according to our research. Despite the fact that additional research works were studied in the previous literature review, there are some study concerns for not correcting third-party data hacking. Therefore, this paper focuses on the design of Secured Quantum Key Distribution (SQKD) with Fuzzy logic to improve the security of the shared key. Quantum Key Distribution, Post Quantum Key Distribution, and the EPR Proto-col are technologies that increase the security of data sharing. We have incorporated the Secured Quantum Key Distribution (SQKD) with Fuzzy logic in our proposed work to improve the security of the shared key. The proposed systems include some additional characteristics in addition to the existing approaches. The proposed model uses shifting algorithms and the fuzzification procedure to assure the security of the secret key in the Fuzzification of Quantum Key approach. The experimental results states that the mean value of security losses in SFQ is 1.8306051, and the mean value of QKD is 14.6448416, with standard deviations of 1.7329 and 13.863 for SFQ and QKD, respectively.
Geospatial fog computing system offers various benefits as a platform for geospatial computing services closer to the end users, including very low latency, good mobility, precise position awareness, and widespread distribution. In recent years, it has grown quickly. Fog nodes' security is susceptible to a number of assaults, including denial of service and resource abuse, because to their widespread distribution, complex network environments, and restricted resource availability. This paper proposes a Quantum Key Distribution (QKD)-based geospatial quantum fog computing environment that offers a symmetric secret key negotiation protocol that can preserve information-theoretic security. In QKD, after being negotiated between any two fog nodes, the secret keys can be given to several users in various locations to maintain forward secrecy and long-term protection. The new geospatial quantum fog computing environment proposed in this work is able to successfully withstand a variety of fog computing assaults and enhances information security.
Several consumers are concerned about the security of their data kept in the cloud, and many see local servers as a safer choice due to perceived control. However, cloud service companies frequently promise greater security procedures and employ dedicated security specialists, making data stored in the cloud potentially more secure. When the data holder expires, new files are saved in the cloud and encrypted with the QAES technology. The data owner then receives the encrypted data request. The sender and user both analyze data before sending encoded documents to the cloud. The key will be used to remove encryption from subsequent data. If users are unable to access the desired data, they should submit a fresh request. The most recent innovation focuses on combining an enhanced form of Quantum Key Distribution (QKD) with AES. This integration resulted in Quantum-AES (QAES), a novel quantum symmetric encryption scheme. QAES is based on the development of a quantum encryption key using dynamic quantum S-Boxes (DQS-Boxes), as opposed to the frequently utilized static S-Boxes. This strategy enhances security. Comparably, time is required to build files faster than they do now. This approach prevents brute force attacks since it uses the QAES algorithm, which provides additional security.
