Sokratis 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 Rector of the Open University of Cyprus, Nicosia, Cyprus, and Professor with the Center for Cyber and Information Security, Department of Information Security and Communications, Norwegian University of Science and Technology, Norway. His research interests lie in the areas of information and communication systems security and of estimation theory and its applications. His research activity over the past 30 years has resulted in the publication of 39 books; 35 book chapters; 86 journal publications (of which 9 invited); and 130 publications in conference proceedings (of which 30 invited). According to Googlescholar, his research work has been cited 3.085 times and his h-index is 27. He has participated in more than 60 funded national and international R&D projects in his areas of research interest. He is serving on the editorial board of several scientific journals, and has served on/chaired the technical programme committee of more than 600 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.
