Research Interests

My research interests lie at the intersection of cryptography, digital hardware design, and computer architecture. I implement the cryptographic protocols (lightweight and post-quantum) on hardware platforms and suggest the possible optimization strategies. The goal of my research is to gain maximum efficiency with respect to computation time and hardware area consumption, simultaneously, as there exist a deep trade-off between both of these two parameters. Further, I work to make the implementations application specific and address the cyberattacks that deliberately target hardware layer vulnerabilities, especially for Internet of Things (IoT) applications. I work with the FPGA and microcontroller implementations, however FPGAs are main focus.
