    Welcome to my web-home!

    The following is a quick timeline overview of my academic background and work experience before I took up the current position.

    Between August 2018 and November 2018, I worked as a visiting lecturer at the R. C. Bose Centre for Cryptology and Security, Indian Statistical Institute.

    From December 2016 to July 2018, I have worked as a visiting scientist at the Turing Lab, Applied Statistics Unit, Indian Statistical Institute.

    From February 2015 to November 2016, I have worked as a post-doctoral researcher at the AriC team, LIP laboratory [CNRS, ENSL, INRIA, UCBL, U. Lyon] of ENS-Lyon. I worked on the PALSE project titled “Towards practical enhanced asymmetric encryption schemes” coordinated by Dr. Benoit Libert.

    I defended my PhD thesis titled “Tree-Based Symmetric Key Broadcast Encryption” on 8th October, 2015. My PhD supervisor was Prof. Palash Sarkar.

    Implementations of the algorithms proposed in my thesis and other related programs can be found here.

    I did my Bachelor of Engineering in Information Technology from Jadavpur University during 2001-05. I did my Master of Technology in Computer Science from Indian Statistical Institute during 2007-09.

    My research interests are primarily in the areas of cryptography, blockchains, security and voting games.



    I have worked on symmetric key broadcast encryption, asymmetric key cryptography and side-channel attacks. 

    I have worked on the interplay between blockchains and voting games. I am also working on the security and efficiency aspects of blockchains.

    I have worked on several problems in voting games - on correlation and inequality in voting power measures, and application of theory of voting games in various practical scenarios like modelling blockchain security and rule change methods, the voting procedure in the Goods and Services Tax (GST) council of India.
