Prof. Ronald Cramer founded the Cryptology group at CWI in 2004. He is Full Professor of Mathematics at Leiden University, also since 2004. Cramer is an internationally recognized leader in the field of cryptology. He is perhaps best known for his contributions to the area of practical reductionist security (especially, CCA-secure encryption and hash proof systems), to the theory of Sigma-protocols, to cryptographic protocol theory (including secure computation) and to arithmetic secret sharing. He is on the editorial board of several journals, including IACR Journal of Cryptology, IEEE Transactions on Information Theory, Journal of Mathematical Cryptology. He served as Program Chair of the 9th Annual IACR TCC (2012), the 24th Annual IACR EUROCRYPT (2005) and the 11th Annual IACR PKC (2008). Selected honors include Fellow of the International Association for Cryptologic Research (IACR), Member of the Royal Netherlands Academy of Arts and Sciences (KNAW), both since 2013, Invited Speaker at the 30th Annual IACR EUROCRYPT (2011), 2006 NWO VICI Senior Career Development Grant, 2003 Distinguished Cryptographer Lecture Series NTT Research, Tokio, and 1998 KNAW Christiaan Huygens Award for his PhD thesis
Dr. Serge Fehr is a senior researcher in the Cryptology group at CWI in Amsterdam. He has a MSc in pure mathematics and a PhD in computer science. His main area of research is on the mathematical foundations of cryptographic security, with a focus on cryptographic protocols that offer information-theoretic security, ranging from secure computation to quantum cryptography, and on the resulting connections between mathematics, computer science and physics. He is a recognized member of the international cryptology research community with regular publications at the distinguished international cryptology conferences CRYPTO and EUROCRYPT, organized by the International Association for Cryptologic Research (IACR). He was/is program chair of the 5th annual ICITS (2011) and the 20th annual IACR PKC (2017) conferences, and he serves on the editorial board of the IACR Journal of Cryptology. Since 2014, he acts as a management committee member of the EU CryptoAction: Cryptography for Secure Digital Interaction, and he is a member of QuSoft, the recently established Dutch Research Center For Quantum Software.
