PhD student
Bar Ilan University
interested in Cryptography

Hello!

I am currently a PhD student at Bar-Ilan University under the supervision of Prof. Carmit Hazay. I have completed my Master's degree in CSE specializing in Cryptography from IIT Bombay. I did my Master's thesis under Prof. Manoj Prabhakaran. I have also worked closely with Prof. Bernard Menezes in the areas of Cryptanalysis and Homomorphic Encryption. I was a Research Assistant in the ISRDC (Information Security Research and Development Center) where my work focused on blockchain and Distributed Ledger Technology.

Research

During the course of my PhD, my research work deals with multi-party computation (MPC), specifically outsoursed computation and MPC-as-a-Service. My PhD thesis focusses on designing garbled circuits based solutions for the same. My other research areas include designing MPC protocols for a wide range of settings and the design and application of garbling schemes.

My Master's thesis under the guidance of Prof. Manoj Prabhakaran is titled 'CellTree', an architecture for distributed data repositories that aims to serve as an alternative to blockchain technology. It is an original design drawing from existing literature on distributed ledger technology and looking to not only solve the scalability issues in blockchains but also allow for verifiable dynamic data storage.

In the future I would like to dive deeper into the theoretical aspects of cryptography and secure multiparty computation and study other cryptographic primitives.
