I am looking for motivated Postdoc/PhD/MTech candidates interested to work on cryptanalysis/MDS matrices/fully homomorphic encryption/differential privacy, please drop me an email!. You will need some background in cryptology– ideally some advanced courses and research experience. For PhD program you will also need to be admitted to the PhD program at IIITV-ICD.
I am an Assistant Professor at Indian Institute of Information Technology Vadodara (IIITV), International Campus Diu (ICD), Diu (U.T.), INDIA. I was a Research Fellow (hosted by Prof. Biplab Sikdar) at the Department of Electrical & Computer Engineering, National University of Singapore (NUS). Prior to this, I spend three months at University College Cork, Ireland working with Dr. Paolo Palmieri. I worked as a cryptanalyst (2021-2023) at C3iHub, IIT Kanpur, where I was fortunate to be advised by Prof. Manindra Agrawal (Director, IIT Kanpur). I finished my PhD in Mathematics (2016-2021) from IIT Madras under the supervision of Prof. Santanu Sarkar (IIT Madras) and Dr. Ayineedi Venkateswarlu (ISI Chennai Centre). I obtained my master's degree in Mathematics (2012-2014) and bachelor's degree in Mathematics and Computer Science (2009-2012) from University of Allahabad. I am broadly interested in Quantum Cryptography, Cryptanalysis, Differential Privacy, Coding Theory and Finite Fields.
My Erdős number is 3 (Paul Erdős->Florian Luca->Santanu Sarkar->Abhishek Kesarwani) Here is my CV (updated in April 2025).
A paper titled On the lower bound cost of MDS matrices, is published in Transactions on Symmetric Cryptology, Issue 4, 2023.
A paper titled Recursive MDS matrices over finite commutative rings, is published in Discrete Applied Mathematics, 2021.
My Science story titled My Journey in Labyrinths of Mathematics: The Security Key of Future, is selected for the AWSAR award by the Department of Science and Technology, India, 2019. Please see pages 271-274.
