About

Christian Killer joined the Communication Systems Group (CSG) in February 2019 to obtain his doctoral degree under the supervision of Prof. Dr. Burkhard Stiller. He finished his Master’s Degree in Informatics at the University of Zurich, focussing on Security Management and Visualization in a Blockchain-based Collaborative Defense. During his Master’s, he also completed a Master’s Project Provotum - Privacy, Verifiability, and Auditability in Blockchain-based E-Voting

Research Interest

  • Blockchains and Distributed Ledgers
  • Remote Electronic Voting and Remote Postal Voting
  • Secret Ballot Voting Protocols
  • Security of Electoral Processes
  • Network Security and Penetration Testing
  • Security Management and Visualization

Open Thesis:

Please check here to see list of open thesis.

We are currently developing Provotum 3.0. If you are interested to contribute in the scope of any student theses, project, or independent study, please feel free to reach out to me. Open aspects which require further investigations are in the areas of Security Analyses of Voting Protocols, Formal Verification of Protocols, Extensions and Improvements on a Rust-based Distributed Ledger, as well as Deployment Security Considerations.
