I’m Dhiman Saha. I love computer science and crypto. I mostly work in symmetric crypto particularly cryptanlaysis.

Recently I am focusing on :

  • Automated Cryptanalysis
  • Classical and Quantum Symmetric-Key Cryptanalysis
  • Lightweight Cryptography
  • Lattice Based Cryptography

My research group calls itself the de.ci.phe.red LAB.
