Outline Activities
For research on cryptography, I am mainly working on secure multiparty computation, mathematical security evaluation of cryptographic technology such as post-quantum cryptography, and fundamental theory such as the usage of pseudorandom generators. For research on mathematics, I am mainly working on combinatorial group theory such as the theory of Coxeter groups, and combinatorics/discrete mathematics. I also worked as PC members of international conferences including ACM ASIACCS 2021.
