About Me
My main research focus is on the implementation security (mainly fault cryptanalysis aspect) of cryptographic algorithms.
I am also interested in the following topics:
- Efficient implementation of SAT/SMT solvers
- Theorem provers and their applications
- Web3 and decentralized networks
I also love typesetting related stuff.
