Some Background Information
I am Sumit Alam Khan (aka lolipop 🍭), a Crypto player from team IUT GENESIS, Islamic University of Technology, Bangladesh. I have been studying Computer Science and Engineering at Islamic University of Technology since January 2020.
Started playing CTFs regularly since June 2021. When I’m not playing with my university team, I play solo with the most random team names possible. (Update: I have been recruited by the well known international team called DeadSec.)
Also a competitive programmer(used to be actually).
I have graduated University on June 28th 2024. And currently joined as a lecturer at a private university(BUBT).
Was an intern at Tree plus plus.
I want to pursue a career in cryptographic research in the future(even though I am terrible at math 😫). Currently looking for PhD opportunities abroad related to Cryptography. Preferebly zero-knowledge proofs or Homomorphic Encryption.
