Hugo Krawczyk
Hugo Krawczyk is an Argentine Israeli cryptographer best known for co-inventing the HMAC message authentication algorithm and contributing to the cryptographic architecture of many Internet standards, including IPsec, IKE, and SSL/TLS.

Education
Krawczyk acquired a Bachelor of Arts with a specialization in Mathematics from the University of Haifa. Later he received his Master of Arts and Ph.D. in Computer Science from Technion - Israel Institute of Technology.

Career
Hugo Krawczyk works at the Algorand Foundation as a Research Fellow. Prior to that, he worked at the IBM T.J. Watson Research Center as an IBM Fellow and Distinguished Research Staff Member, where he was a member of the cryptography research group from 1992 to 1997 and again from 2004 to 2019. He also worked as an Associate Professor in the Department of Electrical Engineering at the Technion in Israel from 1997 until 2004.

Hugo's research interests include both theoretical and applied elements of cryptography, with a focus on network security, privacy, and authentication. TLS 1.3, the next-generation TLS, and HKDF, the emerging standard for key derivation embraced by TLS 1.3, Signal, WhatsApp, Facebook Messenger, and others, are among his most recent projects in this area.
