Security and Privacy in Blockchains and the IoT—3rd Edition

Dear Colleagues,

In recent years, the emergence of blockchain technologies and the Internet of Things (IoT) has shaped a dynamic and innovative landscape that has the potential to leave a lasting mark on our digital society. Blockchains, originally developed as a means to secure decentralized digital currencies, have now outgrown their original purpose and transformed a wide range of application areas, while the IoT has enabled a multitude of devices and sensors to connect, collaborate, and share data. These disruptive technologies have already impacted our daily lives, businesses, and society as a whole, introducing a plethora of novel opportunities and challenges.

Amid this profound digital transformation, the need for ensuring security and privacy within blockchain and IoT ecosystems has become increasingly evident. The synergy between these two technologies is promising yet also entails multiple security and privacy issues that require comprehensive research. Resilient data and transaction security, protection of sensitive information, and preservation of user privacy are essential aspects of a sustainable and trustworthy blockchain and IoT infrastructure. In addition, trust in both the underlying technologies and the data they process is also a key factor in this context.

In this regard, trust in technology, particularly in the security and reliability of blockchain and IoT systems, is fundamental to their widespread adoption and use. Users must have confidence in the resilience of these systems to cyber threats and the integrity of the data they process. Trust in data concerns the veracity and authenticity of information provided by these systems. As the data collected and processed by IoT devices often form the foundation for decisions in a variety of areas, from healthcare to supply chain management, ensuring the trustworthiness of these data is therefore of paramount importance.

With the two successful previous volumes of this Special Issue having already covered a wide range of security and privacy aspects in blockchain and IoT environments, this third volume also aims to spotlight trust issues and the correlations between these three topics. We seek to bring together researchers, experts, and practitioners in the fields of security, privacy, and trust to foster multidisciplinary approaches to solving the pressing resilience problems regarding the application of blockchain and IoT technologies. Within this context, we invite submissions of high-quality research papers, comprehensive review articles, and insightful case studies. Our goal is to provide a platform for sharing innovative approaches, best practices, and insightful lessons learned.
