Special Issue Information

Dear Colleagues,

The Internet of Things (IoT) has become a part of our daily lives, and it has changed our ways of working, studying, consuming entertainment, etc. It enables massive connectivity, automation, and self-decision-making processes in different situations. IoT devices could be different in their behaviors and roles. Each IoT device has a particular task: gathering data, processing data, communicating, and acting. For example, IoT sensors play an essential role in collecting a massive amount of data from different places under different conditions; then, the processing units act as smart units for processing data in order to reply to particular actions. The actions could be transferred as data transmission over a network channel using communication modules or directly transferred to actuators such as motors, robotic arms, etc.

Cybersecurity is considered one of the most essential topics in IoT, as a cyber-attack to a system could lead to severe impact. For example, "hijacking" the connection between an IoT and the other communicated terminals could give the attacker the possibility of stealing data packets and replacing them with compromised ones. That could impact confidentiality, integrity, or the availability of data or system assets, and has undesirable consequences for safety, operation, or privacy. Furthermore, cybersecurity plays an essential role in IoT, defining procedures and strategies to support building safe, secure, and reliable applications. It also protects sensitive data, prevents unauthorized access, and reaches the main security objectives for protecting data, assets, and other sensitive information from malicious activity.

In this Special Issue, we aim to cover cybersecurity topics related to IoT applications in order to find new innovative approaches and strategies to build a secure IoT application for future use. We welcome theoretical and experimental approaches in our Special Issue to provide the research community with new innovative discoveries in cybersecurity.

Potential topics to be covered:

  1. Security-by-design;
  2. Cryptographic mechanisms;
  3. Security communication protocols;
  4. Security policies;
  5. Threat modeling;
  6. Risk management;
  7. Data protection and privacy;
  8. Security requirements;
  9. Security testing;
  10. Security verification and validation;
  11. Transportation cybersecurity (e.g., automotive, railway, avionics, etc.).

Security and privacy concerns pose significant obstacles to the widespread adoption of IoT technology. One potential solution to address these concerns is the implementation of cryptographic protocols on resource-constrained IoT edge nodes. However, the limited resources available on these nodes make it challenging to effectively deploy such protocols. In cryptographic systems, finite-field multiplication plays a pivotal role, with its efficiency directly impacting overall performance. To tackle these challenges, we propose an innovative and compact bit-serial systolic layout specifically designed for Montgomery multiplication in the binary-extended field. This novel multiplier structure boasts regular cell architectures and localized communication connections, making it particularly well suited for VLSI implementation. Through a comprehensive complexity analysis, our suggested design demonstrates significant improvements in both area and area–time complexities when compared to existing competitive bit-serial multiplier structures. This makes it an ideal choice for cryptographic systems operating under strict area utilization constraints, such as resource-constrained IoT nodes and tiny embedded devices. Full article

The accurate tracking of every production step and related outcome in a supply chain is a stringent requirement in safety-critical sectors such as civil aviation. In such a framework, trusted traceability and accountability can be reliably and securely managed by means of blockchain-based solutions. Unfortunately, blockchain cannot guarantee the provenance and accuracy of the stored information. To overcome such a limitation, this paper proposes a secure solution to strongly rely on the tracking information of the physical assets in the supply chain. The proposed solution exploits Hardware Security Modules (HSMs) to provide required cryptographic primitives through a Near-Field Communication (NFC) connection. In our approach, each transfer of the assets is authenticated, verified, and recorded in the blockchain through the HSM. Transaction entries are signed, thus providing a guarantee of ownership and authenticity. The proposed infrastructure has been subject of an exhaustive security analysis and proved resilient against counterfeiting attempts, stakeholder repudiations, and misleading information.
