Jana Sotáková
I specialized in isogeny-based cryptography.
My PhD thesis is publicly available; see below for other formats.
The video of the defense is also available.
I was supervisted by Christian Schaffner, Serge Fehr and Peter Bruin at Institute for Logic, Language and Computation at the University of Amsterdam (ILLC) and a part of the QuSoft Crypto group.
I am not on the academic job market anymore and will leave academic research upon graduation.
Feel free to contact me if you wish to know my reasons. During my PhD, I was interested in:
- post-quantum cryptography, especially isogeny-based cryptography,
- computational number theory,
- quantum algorithms used for cryptanalysis,
PhD Thesis
My PhD thesis, called "Isogenies and cryptography", is available:- from the library;
- as a pdf without the cover (with color hyperlinks);
- as a black-and-white printer-friendly pdf;
- or you can separately admire the cover, but you need to read the thesis to understand why I chose this picture.
Upon my graduation, I hope to put out an updated version incorporating the feedback I received from my committee. Please let me know if you have any comments or remarks or ideas about what parts could be interesting stand-alone.
I also plan to clean up the notebook generating pixel graphs for isogeny graphs (starting from an adjacency matrix).
The video of the defense is available. It starts with a 10 minute layman's talk, followed by 45 minutes of questioning, followed by the awarding of the degree.
