Hello World! Also visit dhimans.in to know more about me.

I am an Assistant Professor at Department of EECS, IIT Bhilai. I love computer science and crypto. I mostly work in symmetric crypto particularly cryptanlaysis. Currently I am exploring the area of Lightweight Cryptography and Quantum Cryptanalysis. My research group focuses on various aspects of computer security and cryptography. The group can be reached at de.ci.phe.red.
