About

I am Mohammad Ferry Husnil Arif, a recent Computer Science graduate from Universitas Indonesia. I became interested in cryptography through CTF competitions, where I saw how abstract mathematics underlies real world security, and this gradually led me toward theoretical cryptography at the interface of mathematics and computer science.

Research Interest

I came to cryptography through my interest in algebra and number theory, where objects like groups, elliptic curves, and lattices underpin security guarantees. More broadly, I am also interested at theoretical computer science that connect with cryptography particularly in complexity theory and quantum computing.
