Roy, Partha Sarathi

Overview

I am a lecturer at School of Computing and Information Technology; University of Wollongong.
Previously, I was a research engineer at Information Security Laboratory, KDDI Research. Before that, I was an Assistant Professor at Graduate School of Information Science and Electrical Engineering, Kyushu University. I completed my Ph.D. on Cryptography at Department of Pure Mathematics, University of Calcutta.
