For such services, it is essential to collect large amounts of data, link and enrich them, and then make them available for processing. Since smart services are also used in critical infrastructures that handle sensitive data, special attention must be paid to security aspects. For instance, authenticity and veracity must be considered when acquiring data; confidentiality and integrity must be ensured when distributing and storing data; and privacy requirements must be respected when processing and provisioning data, to name just a few of such relevant security aspects. Therefore, the aim of the second volume of this Special Issue is to provide a holistic overview of all of these security aspects in the context of the Internet of Things and blockchain systems. This includes research reports on technical or organizational innovations, surveys regarding the state of the research, legal or practical opinions on state-of-the-art technologies, as well as experience reports by domain experts. Both in-depth research on individual security aspects relevant to the Internet of Things and blockchain systems, as well as large-scale views on end-to-end data flows from acquisition to provisioning are welcome.
