Title: Byzantine fault tolerance in the age of Internet of Things
Speaker: Hans P. Reiser (Passau Institute of Digital Security, University of Passau)

Where: FCUL, room 6.3.27

Abstract: In the past twenty years, the Internet of things has become reality. We have reached a situation in which networked smart things outnumber networked traditional computers. Our daily life stronger than ever depends on the correct functionality of all these items and the underlying infrastructure. In this talk we explore the fault tolerance and resilience of Internet-of-things infrastructures. In particular, we argue that due to inherent characteristics, these systems are more than ever prone to accidental and malicious non-crash faults. Based on some of our prior work we explore new directions towards integrating Byzantine fault tolerance in event-based IoT architectures and the deploying BFT CRDTs in hierarchical IoT infrastructures.

Bio: Hans P. Reiser currently is a professor at University of Passau, Germany, associated with the Passau Institute of Digital Security (PIDS). He will join Reykjavik University, Iceland, in January 2022. He graduated in computer science at University of Erlangen and holds a PhD (Dr. rer. nat.) in the area of middleware for fault-tolerant systems from Ulm University. Hans P. Reiser’s research focus is on building distributed systems that are able to mask, detect, and analyze malicious faults.
