Matthias J.
Kannwischer

PhD Student

Info

I'm a PhD student of Peter Schwabe and I am currently finalising my PhD thesis while being a researcher at the Institute of Information Science of Academia Sinica in Taipei, Taiwan.
Previously, I was at the Max Planck Institute for Security and Privacy in Bochum, Germany and the Digital Security group at Radboud University, Nijmegen, The Netherlands.
My second supervisor is Bo-Yin Yang of the Institute of Information Science at Academia Sinica, Taipei, Taiwan.
My current research focus is real-world post-quantum cryptography covering implementation and implementation attacks.
I'm one of the submitters of the Rainbow Signature Scheme which is one of the three NISTPQC signature finalists.
Previously, I was working with Liqun Chen at the University of Surrey.
Before that, I completed my MSc in IT Security at TU Darmstadt. My Master Thesis about implementation attack vulnerabilities of hash-based signatures was supervised by Juliane Krämer and Denis Butin.
