High security solutions are highly important in wireless medical environments, since patient data is confidential, sensitive and must be transmitted over a secure connection. Accordingly, a hybrid encryption method is proposed to ensure data confidentiality (RSA-2048 for key exchange using ACL in SDN with the addition of AES-256-CTR and a hashed secret key for data encryption), and the encrypted data is stored in a private blockchain with the DBFT consensus algorithm to ensure the integrity of data before it being accessed by a doctor's application which decrypts and displays the relevant information. The system was programmed using Python, in an NS3.37 simulator installed on Ubuntu with a MySQL database created using the Apache XAMPP. The product turned out to be a highly secure system for transmitting data from a medical sensor to the doctor's application, offering a throughput of approximately 9 Gbps for both encryption and decryption tasks, while the processing time equaled 0.014 µs per a 128-bit block size for both encryption and decryption, with latency amounting to 0.14 s per 1 KB of data, and the blockchain agreement time equaling 4 ms per 1 KB.

Blockchain has been growing rapidly in the cryptocurrency age and is one of the best information technologies that provide security and privacy to the data of people in crypto economy. In most cases, tampering with data and problems regarding data authentication tend to occur when data is shared and stored on centralized servers. With the assistance of blockchain technology, big data can be managed and saved in the cloud, and the technologies that enhance security by keeping out pernicious users could be used. Therefore, this paper has two aims: to discover the advantages and disadvantages of existing security big data models and to develop a conceptual secure big data model based on blockchain technology. The design science method is used for the purposes of this study. The developed conceptual secure big data model consists of three main processes: dataset storage and encryption, verification and consensus, and access control mechanism. The finding of this study discovered that the developed conceptual secure big data model offers a mix of both traditional and modern security measures which helps domain practitioners understand the security concepts of the blockchain along with big data as well.

The influence of artificial intelligence (AI) in smart cities has resulted in enhanced efficiency, accessibility, and improved quality of life. However, this integration has brought forth new challenges, particularly concerning data security and privacy due to the widespread use of Internet of Things (IoT) technologies. The article aims to provide a classification of scientific research relating to artificial intelligence in smart city issues and to identify emerging directions of future research. A systematic literature review based on bibliometric analysis of Scopus and Web of Science databases was conducted for the study. Research query included TITLE-ABS-KEY (“smart city” AND “artificial intelligence”) in the case of Scopus and TS = (“smart city” AND “artificial intelligence”) in the case of the Web of Sciences database. For the purpose of the analysis, 3101 publication records were qualified. Based on bibliometric analysis, seven research areas were identified: safety, living, energy, mobility, health, pollution, and industry. Urban mobility has seen significant innovations through AI applications, such as autonomous vehicles (AVs), electric vehicles (EVs), and unmanned aerial vehicles (UAVs), yet security concerns persist, necessitating further research in this area. AI’s impact extends to energy management and sustainability practices, demanding standardised regulations to guide future research in renewable energy adoption and developing integrated local energy systems. Additionally, AI’s applications in health, environmental management, and the industrial sector require further investigation to address data handling, privacy, security, and societal implications, ensuring responsible and sustainable digitisation in smart cities.

Software-Defined Networks (SDN) advocate the segregation of network control logic, forwarding functions and management applications into different planes to achieve network programmability and automated and dynamic flow control in next-generation networks. It promotes the deployment of novel and augmented network-management functions in order to have flexible, robust, scalable, and cost-effective network deployments. All of these features introduce new research challenges and require secure communication protocols among segregated network planes. This manuscript focuses on the security issue of the southbound interface that operates between the SDN control and the data plane. We have highlighted the security threats that are associated with an unprotected southbound interface and those issues that are related to the existing TLS-based security solution. A lightweight blockchain-based decentralized security solution is proposed for the southbound interface to secure the resources of logically centralized SDN controllers and distributed forwarding devices from opponents. The proposed mechanism can operate in multi-domain SDN deployment and can be used with a wide range of network controllers and data plane devices. In addition to this, the proposed security solution has been analyzed in terms of its security features, communication, and re-authentication overhead.

Recently, blockchain technology has garnered a great deal of support; however, an attenuating factor to its global adoption in certain use cases is privacypreservation (owing to its inherent transparency). A widely explored cryptographic option to address this challenge has been a ring signature that, aside from its privacy guarantee, must be double-spending resistant. In this paper, we identify and prove a catastrophic flaw for double-spending attacks in a lightweight ring signature scheme and proceed to construct a new fortified commitment scheme that uses a signer’s entire private key. Subsequently, we compute a stronger key image to yield a double-spending-resistant signature scheme that is solidly backed by formal proof. Inherent in our solution is a novel, zero-knowledge-based, secure, and cost-effective smart contract for public key aggregation. We test our solution on a private blockchain as well as a Kovan testnet along with a performance analysis that attests to its efficiency and usability – and, we make the code publicly available on GitHub.

Cloud computing provides centralized computing services to the user on demand. Despite this sophisticated service, it suffers from single-point failure, which blocks the entire system. Many security operations consider this single-point failure, which demands alternate security solutions to the aforesaid problem. Blockchain technology provides a corrective measure to a single-point failure with the decentralized operation. The devices communicating in the cloud environment range from small IoT devices to large cloud data storage. The nodes should be effectively authenticated in a blockchain environment. Mutual authentication is time-efficient when the network is small. However, as the network scales, authentication is less time-efficient, and dynamic scalability is not possible with smart contract-based authentication. To address this issue, the blockchain node runs the skip graph algorithm to retrieve the registered node. The skip graph algorithm possesses scalability and decentralized nature, and retrieves a node by finding the longest prefix matching. The worst time complexity is O(log n) for maximum n nodes. This method ensures fast nodal retrieval in the mutual authentication process. The proposed search by name id algorithm through skip graph is efficient compared with the state-of-art existing work and the performance is also good compared with the existing work where the latency is reduced by 30–80%, and the power consumption is reduced by 32–50% compared to other considered approaches.

Dematerialisation of bills of lading is an important topic from the point of view of maritime transport practice. There are many arguments in favour of dematerialisation, such as simplification and acceleration of trade. Over the years, many attempts have been made to dematerialise bills of lading using EDI systems. All of them were found to be lacking. It was not until the spread of blockchain technology that adequate tools were found. The blockchain makes it possible to meet the requirement of singularity which was haunting the EDI systems. With the introduction of proper provisions of law and if the maritime transport industry could agree on a mutually compatible standard, blockchain-based bills of lading could successfully replace paper bills of lading.

The globalization of markets has resulted in the need to develop supply chains and ensure efficient connections between entities in various remote locations. The dissemination of information technologies has made it possible to increase the excellence of the supply chain, responding to the needs arising from globalization and thus influencing the efficiency of the processes carried out by optimizing the use of resources and implementing new management strategies. Information transfer between its links significantly impacts the supply chain's reliability, safety, and costs of material flow. The introduction of electronic communication significantly accelerated and facilitated the transfer of information and, in some areas, made it possible to abandon traditional paper documentation. Modern digital technologies such as blockchain have the potential to eliminate paper documentation while increasing the security and certainty of the transferred data. This article analyzes the current flow of information and documents in the supply chain. The article presents the characteristics of the supply chain operation in terms of the flow of information accompanying the flow of cargo and the digitization of document circulation in the digital supply chain in the context of using electronic data interchange (EDI) or blockchain. The ELECTRA tool was presented concerning the discussed area, which is being developed as part of the ongoing project (Electronic Waybill for Combined Transport and Forwarding) in the EUREKA initiative, financed by the National Center for Research and Development. This tool combines the latest technological solutions to improve the flow of transport documents. The article ended with a summary, pointing to the potential of using modern solutions and the lack of technological barriers. However, the existing legislative barriers were emphasized.

Globalizacja rynków wpłynęła na konieczność rozwoju łańcuchów dostaw i zapewnienia sprawnego połączenia podmiotów rozmieszczonych w różnych odległych lokalizacjach. Upowszechnienie technologii informacyjnych pozwoliło podnieść doskonałość łańcucha dostaw, odpowiadając na potrzeby wynikające z globalizacji, a tym samym wpływając na efektywność realizowanych procesów przez optymalizację wykorzystania zasobów i wdrażanie nowych strategii zarządzania. Istotny wpływ na niezawodność, bezpieczeństwo, ale i koszty przepływu materiałów w łańcuchu dostaw ma przekazywanie informacji między jego ogniwami. Wprowadzenie komunikacji elektronicznej znacznie przyśpieszyło i ułatwiło przekazywanie informacji i w pewnych obszarach pozwoliło na rezygnację z tradycyjnej dokumentacji papierowej. Nowoczesne technologie cyfrowe takie jak łańcuch bloków (ang. blockchain) mają potencjał, aby całkowicie wyeliminować dokumentację papierową przy jednoczesnym zwiększeniu bezpieczeństwa i pewności przekazywanych danych. Celem niniejszego artykuł jest analiza stanu istniejącego w aspekcie przepływu informacji i dokumentów w łańcuchu dostaw. W artykule przedstawiono charakterystykę funkcjonowania łańcucha dostaw w aspekcie przepływu informacji towarzyszących przepływowi ładunków, a także problematykę cyfryzacji obiegu dokumentów w cyfrowym łańcuchu dostaw w kontekście wykorzystania elektronicznej wymiany danych (EDI – ang. electronic data interchange) czy blockchain.

Different industries are modernising their systems and introducing innovations to their management practices. However, the construction industry is recognised for its lack of technological systems on which the success of this sector is deemed to be heavily dependent. Previous studies have focused on enhancing the off-site construction supply chain. However, studies on the importance and utilisation of technology in this sub-sector are scarce, predominantly where the efficiency of off-site supply chain management is stalled as a consequence of the slow implementation of technology. Thus, this article employs an exploratory approach by providing insight into the applicability of blockchain technology in New Zealand’s off-site construction and demonstrates the benefits associated with the adoption of this technology. A literature review was used to identify stakeholders’ interrelationships in different stages of prefabrication projects. Then, a pilot interview from industry experts followed by a questionnaire survey was used to determine the involvement of stakeholders in different phases and the benefits that blockchain technology can bring to this industry. The results indicate that using blockchain as a secure information management system could improve the integration of prefabrication supply systems by producing a collaborative atmosphere amongst the organisations involved.

The development of blockchain technology and distributed ledgers indeed contributes to enabling the delivery of various digital services, such as financial services, registry management, and tokens, including non-fungible tokens (NFTs). In blockchain systems, decisions are made based on the so-called consensus mechanism, which is a method of selecting a single version of transaction history that all nodes consistently agree upon. Although this technology is classified as emerging, it has a history of over ten years, and its ongoing implementations, including in the public administration sector, demonstrate its evolution and its status as one of the most promising technologies in terms of ensuring data immutability. The published ISO (International Organization for Standardization) standards and numerous implementations using business models executed in the DAO (Decentralized Autonomous Organization) architecture undoubtedly support the development of blockchain.

Using blockchain technology in the Internet of Things (IoT) security is a research trend in recent years. With large IoT networks, miners will have to verify a lot of transactions broadcast from IoT devices. This can cause a delay in saving valid transactions to the ledger. This paper proposes a proof-of-miner-clustering-authentication consensus method of blockchain for IoT networks. In the proposed method, miners in a blockchain network will be clustered, each miner in a cluster is responsible for verifying transactions from IoT devices in the area it manages. Mining of new blocks between clusters is done by the round robin method. Our consensus method can apply to private or consortium blockchain networks, helping to improve the transaction verification speed of miners.
