David Chaum
abstract will follow asap

Elixxir was founded by David Chaum, a pioneer in cryptography and privacy-preserving technologies and widely recognized as the inventor of digital cash. His 1982 work on cryptographic "vault systems" contains the first proposal for a blockchain protocol, containing all but one element detailed 26 years later in the Bitcoin white-paper.
His company DigiCash, created the first digital currency, eCash, in 1995. eCash deployed David's breakthrough cryptographic blind signature protocol to create the world's first attempt at anonymous digital cash. He is also known for creating other fundamental innovations in cryptography like mix networks, the cMix protocol, and secure election systems. With a PhD in Computer Science from UC Berkeley, he taught at NYU Graduate School of Business and the University of California, led a number of breakthrough projects and founded the International Association for Cryptologic Research, the cryptography group at CWI, DigiCash, the Voting Systems Institute, and the Perspectiva Fund.

Claude Crepeau
Demonstrating That a Public Graph Can Be 3-Coloured Without Revealing Any Knowledge About How...
In this talk, we review the early days of Interactive Proofs, Interactive Arguments and other Zero-Knowledge protocols. We highlight Chaum’s contributions to this young (30 years ago) field and where it led us today. We survey current research on Argument Systems, as well as Zero-Knowledge proofs where soundness and zero-knowledge only rest on the assumption that no information can travel faster than the speed of light.

Claude Crépeau is a professor in the School of Computer Science at McGill University. Ηe was born in Montreal, Quebec, Canada, in 1962. He received a master's degree from the Université de Montréal in 1986, and obtained his Ph.D. in Computer Science from MIT in 1990, working in the field of cryptography with Prof. Silvio Micali as his Ph.D. advisor and Gilles Brassard as his M.Sc advisor. He spent two years as a Postdoctoral Fellow at Université d'Orsay, and was a CNRS researcher at École Normale Supérieure from 1992 to 1995. He was appointed associate professor at Université de Montréal in 1995, and has been a faculty member at McGill University since 1998. He was a member of the Canadian Institute for Advanced Research program on Quantum Information Processing from 2002 to 2012. He was nominated as an IACR Fellow in 2013 https://www.iacr.org/fellows/. Prof. Crépeau is mostly known for his fundamental work in zero-knowledge proof, multi-party computing, quantum cryptography, and quantum teleportation.

Serge Fehr
abstract will follow asap

Serge Fehr is a senior researcher in the Cryptology Group at CWI, and a professor of mathematics at Leiden University. He obtained his M.Sc. in mathematics from ETH Zurich (Switzerland) in 1998 and his Ph.D. in computer science from Aarhus University (Denmark) in 2003. He is a leading scientist in the area of cryptography and its connections to mathematics, in particular to algebra and number theory and to quantum information theory and quantum computing.
Serge is also a member of QuSoft, the Dutch research center for quantum software, and of AMSec, the Amsterdam Cyber Security Center. He is on the editorial board of the Journal of Cryptology and of the IEEE Transactions on Information Theory, and he is currently the co-chair of the steering committee of QCrypt, the annual conference on quantum cryptography.

Anna Lysyanskaya
abstract will follow asap

Anna Lysyanskaya is a Professor of Computer Science at Brown University. She received an A.B. in Computer Science and Mathematics from Smith College in 1997, and a Ph.D. in Computer Science and Electrical Engineering from MIT in 2002. She is a recipient of an NSF CAREER award and a Sloan Foundation fellowship and was included in the Technology Review Magazine's list of 35 innovators under 35 for 2007. In 2012, she was elected (and in 2015 and 2018, reelected) a Director of the International Association for Cryptologic Research.  Anna Lysyanskaya's research interests are in cryptography, theoretical computer science, and computer security. A theme of her research, inspired by David Chaum's pioneering work, is on balancing privacy with accountability, and specifically allowing users to prove that they are authorized even while not revealing any additional information about themselves.
