Curiouser and Curiouser!! - Alice in Wonderland

I have grown to love secrecy. It seems to be the one thing that can make modern life mysterious or marvelous to us. The commonest thing is delightful if only one hides it. - Oscar Wilde, The Picture of Dorian Gray
Welcome to my homepage! The above two quotes are from my favorite books and reflect my research interests. My primary interests are in applied cryptography, security, privacy, combinatorics, and social and complex network analysis. I am currently working on security and privacy of clouds, mobile ad hoc networks, vehicular networks, social networks and smart grids. I am interested in designing practical cryptographic protocols for Internet of Things and Cyber-Physical Systems. Blockchain and cryptocurrencies are now big on my agenda.

I joined ISI in May 2013, after a brief but very enjoyable stint as Assistant Professor at Indian Institute of Technology, Indore.

Between May 2010 and July 2012, I was a Post Doctoral Fellow with Prof. Amiya Nayak and Prof. Ivan Stojmenovic in the School of Engineering and Computer Science, University of Ottawa and between August 2009 and April 2010, I was a Erasmus Mundus Post Doctoral Fellow working with Prof. Thomas Johansson at Lund University, Sweden.

I completed my Ph. D. at Indian Statistical Institute, India in 2009. My advisor was Prof. Bimal Roy. My Ph. D. thesis is about applications of combinatorial designs to key predistribution. During my Ph. D., I spent the summers at University of Wollongong, Australia, INRIA Roquencourt, France and Microsoft Research Labs, India.

I received a BE degree in Computer science from Indian Institute of Engineering Science and Technology (IIEST) , formerly known as Bengal Engineering College, Shibpur, India in 2004. It is the second oldest Engineering College in India.

I was born and raised in Durgapur Steel City in India, went to Carmel School, Durgapur Steel township till grade 10 (1998) and then DAV Model School(2000).

My Erdos Number is 2. (via. S.B. Rao)

I am very fond of fish/seafood, green-black-white tea and whenever I get the opportunity, I check out items in my long and ever-increasing want-to-do-list.


I am teaching Information and Coding Theory. (July 2017 - December 2017).
I am looking for motivated Ph. D. and Masters students to work with me on interesting problems. If you are already a student enrolled in ISI, please feel free to drop by my office to know more about my research activities. If you are not enrolled in ISI, please apply to the relevant programs.

I am co-organizing The First ACM Workshop on Blockchain, Cryptocurrencies and Contracts (BCC'17), in conjunction with ACM AsiaCCS'17.
