isogenist & isometrist
I’m a PhD student in the subject post-quantum cryptography at the Digital Security group of the Radboud University, Nijmegen.
The easiest way to reach me is to send me an e-mail: krijn@cs.ru.nl
This is my website, that serves to host some of my (professional) writings, some thoughts that I have at times and an online version of my cv.
Cryptography.
My research focuses on the design and cryptanalysis of post-quantum cryptographic schemes, and at this moment specifically code-based and isogeny-based schemes. You could say that I look at isogenies and isometries. Both admit a cryptographic group action on which you can design all sorts of schemes, although the former is commutative and the latter non-commutative.
Together with Jonathan Eriksen, I organize The Isogeny Club: a bi-weekly virtual seminar for young isogenists.
Commentary.
Sometimes I write things about different thoughts I have on my own personal interests. These should never be taken too seriously.
Consultancy.
Additionally, I provide limited consultancy services, building on my experience as a strategy consultant. This includes, for example, advise on (post-quantum) cryptography, and crypto-trainings in general.
