Hugo Krawczyk

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.

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.[2] He also worked as an Associate Professor in the Department of Electrical Engineering at the Technion in Israel from 1997 until 2004.[3][4]

Hugo's research interests include both theoretical and applied elements of cryptography, with a focus on network security, privacy, and authentication.[5] 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.[6][7]
