Arnab Roy

I am a tenure-track assistant professor at the University of Innsbruck (Department of Computer Science).

Research Interests My research interests lie in the area of cryptography and its applications. I am interested in designing cryptographic primitives, cryptanalysis, and applications of cryptography in security and privacy.

I was a lecturer (2020 - 2023) at the Alpen-Adria Unviersity Klagenfurt in the Cybersecurity Research group led by Prof. Elisabeth Oswald. Prior to that, I was a senior research associate (09/2017 - 2019) at the Unviersity of Bristol, UK in the cryptography research group, and a postdoc researcher (2014 - 2017) at the Technical University of Denmark in the Cybersecurity group hosted by Prof. Christian Rechberger.

I received PhD in Computer Science from the University of Luxembourg in 2014. My doctoral research topic was security aspects of symmetric-key primitives and my thesis supervisor was Prof. Alex Biryukov.

My academic background is in Mathematics. I received master’s (M.Sc from the Indian Institute of Technology, Kanpur) and bachelor’s (B.Sc with Hons. from the University of Calcutta) degrees in Mathematics. I also hold a master’s (M.Tech from the Indian Statistical Institute, Calcutta) degree in Computer Science.
