Research into 5G and IoT Technologies at UTS:
From Spectrum Sharing to Blockchain for Security and Trust
Dr. Eryk Dutkiewicz Professor
School Head of Electrical and Data Engineering (University of Technology Sydney, Australia)
5G and Internet of Things technologies have the potential to enable many new applications and bring economic benefits. There are, however, many challenges that need to be overcome to make them useful. In this presentation we focus on research conducted at University of Technology Sydney (UTS) addressing two such challenges: spectrum sharing and security and trust. Spectrum sharing is regarded as an essential approach to regaining access to otherwise unused spectrum and it is considered an essential component in the development of IoT and 5G networks. Efficient decisions regarding the use of spectrum sharing require accurate knowledge of the spatial and temporal spectrum use. This knowledge can be represented in Radio Environment Maps which need to be generated efficiently and accurately. Radio Environment Maps can also be used for policing and enforcement of spectrum use for security purposes. Security and trust are also essential elements associated with Internet of Things networks and applications. In this presentation we discuss Internet of Things technologies and applications as well as their security and trust aspects. Subsequently we describe the concept of the blockchain which was originally designed for secure financial transactions. Its cryptographic security benefits, including user anonymity, fault tolerance, transaction integrity and authentication, can be used to enable security and privacy in Internet of Things. We discuss the benefits, limitations and challenges of using blockchain with Internet of Things. We also describe our IoT-blockchain testbed and overview several of our current IoT-blockchain projects for supply chain tracking.
