Special Issue Information

Dear Colleagues,

Blockchain technology was designed to enable decentralized and secure crypto-currency.

Numerous studies have explored the features of blockchains, such as scalability, resiliency, decentralization, reliability, and immutability in different use cases. Hence, blockchains are becoming a cornerstone for the development and deployment of other technologies such as decentralized applications (Dapp), the Internet of Things (IoT), digital supply chains (DSCs), cooperative intelligent transportation systems (C-ITSs), federated learning (FL), and many others.

Blockchain is still a growing technology, and it has the potential to disrupt numerous technologies in the future. However, as an evolving technology, it is suffering from many setbacks; the most severe are from the security perspective.

This Special Issue calls for research contributions on how blockchains can ensure the security of systems and environments, and the different security issues related to blockchain-based technologies and architectures. More precisely, the topics of interests in this Special Issue include, but are not limited to:

  • Blockchain-based approaches for the security of IT systems;
  • Blockchain-based approaches for intrusion detection;
  • Blockchain issues and trends;
  • Blockchain privacy;
  • Blockchain new design;
  • Cryptocurrency fraud;
  • Cryptocurrency fraud detection;
  • Smart contracts for the security of IT systems;
  • Smart contracts privacy and security issues.

Advances in communications technology have had tremendous influence on network implementation to date, and as communication devices get smaller and technologies more intelligent, a great number of solutions are emerging that converge communications with a multitude of domains. In particular, as transportation modes assisting with mobility have developed, many studies are in the pipeline on the domain of mobility. The development of mobility services has prompted the spread of car sharing, which also highlights the need for a system that controls shared vehicles. The data of such control system can be used not only for the operational management of vehicles but also the management of users in terms of user driving analysis or monitoring safe driving. In addition, it can be utilized in a variety of other applications that analyze traffic flow based on vehicle driving data, determine required vehicle maintenance intervals, or schedule vehicle maintenance in advance. However, if forged/altered by a third party, control data might pose a lot of challenges to data utilization. This study proposes a mechanism that manages control data on a blockchain to enhance the integrity of control data created in the communications process. In this paper, we propose a mechanism for applying a blockchain to the communication process between clients and servers. In the proposed mechanism, platform operators generate and provide independent identification information and identification numbers for users. The identification information and identification numbers are used to prove that the generated blocks were created by specific users. Data generated by clients create a block with a hash including user identification information alongside the user identification number. Verification of the generated block is performed on the platform vendor’s server, validating that the user identification number in the block matches the server-side user identification information and the hash of the data within the block. Thus, even when the contents of the block are shared in a public blockchain environment, user identification information is only held by the server and clients, preventing third parties from impersonating specific users to create data blocks. Furthermore, the verification process of the data includes hashes received from other nearby vehicles, preventing data tampering by the block creator. Full article

Blockchain transactions are decentralized, secure, and transparent, and they have altered industries. However, the emergence of quantum computing presents a severe security risk to the traditional encryption algorithms used in blockchain. Post-quantum signatures are required to preserve integrity and reliability. Furthermore, combining the InterPlanetary File System (IPFS) with blockchain provides a long-term strategy for data storage and sharing. This study investigates the integration of post-quantum signatures with the IPFS in a blockchain system, which can considerably enhance blockchain system efficiency. We increase security and efficiency by recording hash values of signatures and public keys within the blockchain and storing their actual content using the IPFS. The study compares NIST-recommended post-quantum signatures with the ECDSA in a Bitcoin exchange scheme to show how effective the system is in countering quantum threats while maintaining optimal performance. This research makes an important addition to the long-term viability and dependability of blockchain technology in the face of the growing landscape of quantum computing breakthroughs. Full article
