Leveraging Blockchain Technology to Enhance Security and Privacy in the Internet of Things

Sokratis K. Katsikas
Norwegian University of Science and Technology

Brief Bio
Sokratis K. Katsikas was born in Athens, Greece, in 1960. He received the Diploma in Electrical Engineering from the University of Patras, Patras, Greece in 1982, the Master of Science in Electrical & Computer Engineering degree from the University of Massachusetts at Amherst, Amherst, USA, in 1984 and the Ph.D. in Computer Engineering & Informatics from the University of Patras, Patras, Greece in 1987. In 2019 he has awarded a Doctorate Honoris Causa by the Dept. of Production and Management Engineering of the Democritus University of Thrace, Greece. He is the Director of the Norwegian Center for Cybersecurity in Critical Sectors and Professor with the Department of Information Security and Communication Technology, Norwegian University of Science and Technology, Norway. His current research interests lie in the area of information and communication systems security. His research activity over the past 35 years has resulted in the publication of 44 books; 38 book chapters; 99 journal publications (of which 9 invited); and 131 publications in conference proceedings (of which 30 invited). He has participated in more than 60 funded national and international R&D projects. He is serving on the editorial board of several scientific journals, and has served on/chaired the technical programme committee of more than 750 international scientific conferences. He chairs the Steering Committee of the ESORICS Conferences.

The Internet of Things (IoT) and Blockchain are two technologies that have dramatically changed the traditional computing models. While the IoT has enabled multiple new computing applications, it has also raised significant issues regarding security and privacy, as lightweight devices with limited resources, scattered in terms of network topology and too diverse in terms of hardware and software are nowadays used for processing huge amounts of data, including sensitive data. On the other hand, blockchain technology enables the development of secure decentralized systems and offers guarantees regarding data integrity, application logic integrity and service availability. Thus, the idea to explore the potential of employing Blockchain technology to solve some of the main security and privacy issues encountered in the IoT it seems promising. In this talk we will discuss the convergence of the two technologies, we will analyze use cases of blockchain in the IoT and the encountered difficulties therein, and we will discuss possible research directions towards enhancing the applicability of blockchain technology to the IoT domain.

Stefan Schmid
University of Vienna

Brief Bio
Stefan Schmid is a Professor at the Faculty of Computer Science, at University of Vienna, Austria. He obtained his diploma (MSc) in Computer Science at ETH Zurich in Switzerland (minor: micro/macro economics, internship: CERN) and did his PhD in the Distributed Computing Group led by Prof. Roger Wattenhofer, also at ETH Zurich. As a postdoc, he worked with Prof. Christian Scheideler at the Chair for Efficient Algorithms at the Technical University of Munich and at the Chair for Theory of Distributed Systems at the University of Paderborn, in Germany. From 2009 to 2015, Stefan Schmid was a senior research scientist at the Telekom Innovation Laboratories (T-Labs) and at TU Berlin in Germany (Internet Network Architectures group headed by Prof. Anja Feldmann). In 2013/14, he was an INP Visiting Professor at CNRS (LAAS), Toulouse, France, and in 2014, a Visiting Professor at Université catholique de Louvain (UCL), Louvain-la-Neuve, Belgium. From 2015 to 2017, Stefan Schmid was a (tenured) Associate Professor in the Distributed, Embedded and Intelligent Systems group at Aalborg University, Denmark, and continued working part-time at TU Berlin, Germany. Since 2015, he serves as the Editor of the Distributed Computing Column of the Bulletin of the European Association of Theoretical Computer Science (BEATCS), since 2016 as Associate Editor of IEEE Transactions on Network and Service Management (TNSM), and since 2019 as Editor of IEEE/ACM Transactions on Networking (ToN). Stefan Schmid received the IEEE Communications Society ITC Early Career Award 2016. His research interests revolve around the fundamental and algorithmic problems of networked and distributed systems.

Communication networks have become a critical infrastructure of our digital society. But how much can we trust our networks today?
Over the last years, we have witnessed the emergence of interesting new kinds of networks. For example, programmable and virtualized networks introduced unprecedented operational flexibilities in datacenter and wide-area networks. Another example are payment channel networks which are considered a promising solution to the scalability problems of cryptocurrencies such as Bitcoin.
In this talk, I will provide an overview of the novel opportunities and challenges of emerging networking paradigms, in terms of security. In particular, I will show how such networks can increase the attack surface, enabling new attacks such as teleportation, tuple space explosion, exfiltration or denial-of-service on payments. I will then also discuss first ideas for solutions, from efficient isolation mechanisms, algorithmic networking monitoring, to machine learning.
