Blockchain and Cybersecurity

Blockchain and other distributed ledger technologies (DLTs), through recent development, have not only enabled simple transactions, but also complex computation on a network where parties are geographically distant or have no particular trust in each other to interact and exchange value and information on a fully distributed basis with fewer to non-existent central intermediaries. There are obvious advantages associated with blockchain in areas such as decentralization, disintermediation, replication, timestamping, immutability, digital signatures, automation and smart contracts, transparency and censorship resistance, especially in relation with the financial sector. However, there are also noticeable challenges, for instances, scalability and performance, energy consumption, security and privacy. Many popular applications are cloud related. These advances are now not just limited to the financial sector, but also new internet applications can harness these building blocks to empower users to take control of their online footprint, such as in healthcare, social media and other digital services.

Ruxandra F. Olimid is Associate Professor at the Department of Computer Science, University of Bucharest, Romania and Adjunct Associate Professor at the Department of Information Security and Communication Technology, Norwegian University of Science and Technology – NTNU, Trondheim, Norway. She received her Ph.D. in Computer Science from the University of Bucharest in 2013. She has a background in both computer science (BSc and MSc from the University at Bucharest, 2008 and 2010) and telecommunications (BSc from the University Politehnica of Bucharest, 2009). Her past experience in industry was focused on software for telecommunications (almost 10 years as an employee of Orange Romania). Her research interests include privacy and security in communication networks and cryptography.

Chunming Rong has been academician of the Norwegian Academy of Technological Sciences (NTVA) since 2011. He has served the extended IEEE Cloud Computing community for many years. Starting the CloudCom conference series in 2009, he gave numerous keynote addresses at IEEE conferences all over the world. He played a vital leadership role (first as vice chair and then as chair) in both the IEEE Cloud Computing initiative and the IEEE CS STC Cloud Computing, and led its transition to the IEEE CS Technical Committee on Cloud Computing (TCCLD). He served as the steering chair (2016-2019), and now as steering member of the IEEE Transactions on Cloud Computing (TCC). He has extended his engagement also in the IEEE Future Directions, through his involvement with the IEEE Blockchain Initiative (2017-2018). He is an executive member of Technical Consortium on High Performance Computing (TCHPC) and the chair of STC on Blockchain in IEEE Computer Society. He is an IEEE senior member. Prof. Rong is also advisor of the StandICT.EU to support European scandalization activities in ICT. He works as the head of the Data-centered and Secure Computing (DSComputing) at the University of Stavanger (UiS). He is also co-founder of two start-ups bitYoga and Dataunitor in Norway, both received EU Seal of Excellence Award in 2018. He was adjunct Senior Scientist leading Big-Data Initiative at NORCE (2016-2019), the vice president of CSA Norway Chapter (2016-2017). He is co-Editors-in-Chief of the  journal “Blockchain: Research and Applications” by Elsevier, co-Editors-in-Chief of the Journal of Cloud Computing (ISSN: 2192-113X) by Springer, has served as the steering chair (2016-2019), steering member and associate editor of the IEEE Transactions on Cloud Computing (TCC) since 2016. He has extensive contact network and projects in both the industry and academic. His research work focuses on cloud computing, data analytics, cyber security and blockchain. Prof. Rong has extensive experience in managing large-scale R&D projects, both in Norway and EU.
