David is a cryptographer and a professor at the École normale supérieure. He was previously a professor at Panthéon-Assas University. David is well known for his work in public-key cryptography, especially around the cryptanalysis of digital signature schemes. He co-designed the Naccache-Stern cryptosystem and the Naccache-Stern knapsack cryptosystem. David is also a visiting professor and researcher at the Information Security Group of Royal Holloway, University of London, and in 2020, was elected as a Fellow of the IACR.

Paul is a cryptographer and computer security researcher, and is currently a professor of computer science at Carleton University in Ottawa, Ontario. He previously held a Canada Research Chair in authentication and computer security and is a Fellow of the Royal Society of Canada (FRSC). Along with Alfred Menezes and Scott Vanstone, Paul was a co-author of the Handbook of Applied Cryptography, and the author of Computer Security and the Internet. In 2000, he was awarded The J.W. Graham Medal in Computing Innovation, and a Fellow of the Association for Computing Machinery in 2016 for his "contributions to applied cryptography, authentication and computer security.

Craig is a Professor of Computer Science at Queensland University of Technology (QUT), who has a special focus on post-quantum cryptography and Zero Knowledge Proofs. He was previously a Principal Researcher at Microsoft Research at Redmond. Craig did his PhD at QUT from 2008 to 2012, and received a Fulbright Scholarship with UC Irvine from 2010 and 2011. In 2015, Craig published details of the FourQ elliptic curve, and which is one of the fastest curves around.
