Abstract

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.

QKD in Cloud-Fog Computing for Personal Health Record

L. Arulmozhiselvan, E. Uma

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.

The Evolution of Quantum Key Distribution Networks: On the Road to the Qinternet

Yuan Cao, Yongli Zhao, Qin Wang +3 more

Quantum key distribution (QKD) constitutes a symmetric secret key negotiation protocol capable of maintaining information-theoretic security. Given the recent advances in QKD networks, they have evolved from academic research to some preliminary applications. A QKD network consists of two or more QKD nodes interconnected by optical fiber or free space links. The secret keys are negotiated between any pair of QKD nodes, and then they can be delivered to multiple users in various areas for ensuring long-term protection and forward secrecy. We commence by introducing the QKD basics, followed by reviewing the development of QKD networks and their implementation in practice. Subsequently, we describe the general QKD network architecture, its elements, as well as its interfaces and protocols. Next, we provide an in-depth overview of the associated physical layer and network layer solutions, followed by the standardization efforts as well as the application scenarios associated with QKD networks. Finally, we discuss the potential future research directions and provide design guidelines for QKD networks.

Secure Quantum Steganography Protocol for Fog Cloud Internet of Things

Ahmed A. Abd El‐Latif, Bassem Abd-El-Atty, M. Shamim Hossain +2 more

The security of sensitive information is an urgent need in today's communication, principally in cloud and Internet of Things (IoT) environments. Therefore, a well-designed security mechanism should be carefully considered. This paper presents a new framework for secure information in fog cloud IoT. In the framework, the user in one location embeds his/her valuable data via the proposed quantum steganography protocol and uploads the covered data to the fog cloud. The intended receiver in another location accesses the data from the fog cloud and extracts the intended content via the proposed extraction approach. This paper also presents a novel quantum steganography protocol based on hash function and quantum entangled states. To the best of our knowledge, there is no prior quantum steganography protocol that authenticates an embedded secret message. In the suggested protocol, the hash function is utilized to authenticate embedded secret messages. The presented protocol is secure against well-known attacks, such as message, man-in-the-middle, and no-message attacks. In addition, it does not consume additional channels besides the proposed one to send a secret message or verify security. The proposed approach is nominated for use in fog and mobile edge computing.

Quantum-Based QKD and Sugar-Salt Encryption Approach in Cloud-Fog Computing to Strengthen Protection of Online Banking Data

Sapthak Mohajon Turjya, Raj Singh, Pritam Sarkar +2 more

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.

A Quantum-Cryptography-Enhanced Framework for Secure Cloud Computing Using Quantum Key Distribution (Qkd)

R. Jayachandran, D. Malathi

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.
