Abstract: Last few years have seen tremendous progress in the development of technologies towards making of a quantum computer. Number of qubits in the systems are increasing day by day, and thereby quantum algorithm implementations are scaling up big time. Amidst this turmoil, the fate of cryptography is worth investigating. It is now a popular news that public key crypto-systems are broken by quantum algorithms and thereby most of the state-of-the art key agreement protocols are dead. Meanwhile, Quantum key distribution comes to rescue classical key agreement and thereby opens a new paradigm of quantum cryptography. Simultaneously, a lot of research is being performed during the last couple of years on the application of quantum tools to attack classical algorithms. In this talk, we will walk through the interesting interplay of classical and quantum cryptography, and critically analyze their role as competitors as well as collaborators.

Bio: Dr. Goutam Paul completed his Bachelor degree in Computer Engineering from IIEST Shibpur; Master degree in Computer Science from State University of New York (SUNY) at Albany, U.S.A.; and Ph.D. in Cryptology from Indian Statistical Institute. From 2006 to 2013, he was an Assistant Professor in the Department of Compute Science and Engineering of Jadavpur University, Kolkata, India. Currently, Dr. Paul is serving as an Associate Professor at Cryptology and Security Research Unit of Indian Statistical Institute, Kolkata. Dr. Paul received the prestigious Alexander von Humboldt Award in 2012 and thereby visited the Institute for Communication Technologies and Embedded Systems (ICE) at RWTH Aachen University, Germany as a guest scientist for one year. In 2013 Dr. Paul has received the Young Scientist Award from the National Academy of Sciences, India (NASI). Dr. Paul's research area is Classical and Quantum Cryptography.
