Pratish Datta


I received my MSc in Mathematics and PhD in Cryptography from Indian Institute of Technology Kharagpur in 2012 and in 2017 respectively. Since 2017, before joining the CIS Laboratories of NTT Research, Inc. in 2019, I worked as a postdoctoral fellow at the NTT Secure Platform Laboratories in Japan under the supervision of Dr. Tatsuaki Okamoto. My mathematical background laid the foundation for my expertise over a wide range of hybrid strategies of provable security. Designing cryptographic algorithms offering advanced functionalities, featuring practical efficiency, and guaranteeing strong mathematical security at the same time is the central goal of my research endeavors. Specifically, I am interested in the design and analysis of functional encryption, attribute-based encryption, signatures, and pseudorandom functions. My findings have been broadly published within the proceedings of frontline international conferences like ASIACRYPT, PKC, ISC etc., and high-impact international journals like Theoretical Computer Science, Algorithmica etc.
