profile


Hugo Krawczyk is an IBM Fellow and Distinguished Research Staff Member at the IBM T.J. Watson Research Center where he has been part of the cryptography research group from 1992 to 1997 and from 2004 to the present. Between 1997 and 2004 he was an Associate Professor with the Department of Electrical Engineering at the Technion, Israel.

Hugo's areas of research span theoretical and applied aspects of cryptography with particular emphasis on applications for network security, privacy, and authentication. He has worked on the design, analysis and implementation of solutions for data encryption and authentication, key management, public key cryptography, Internet security, electronic commerce, payment systems, and privacy-protecting technologies.

Over the last 20+ years, Hugo has contributed to Internet standards, from the early days of IPsec and IKE to the recent work on revamping the security of TLS for its "next generation" version, TLS 1.3 (RFC 8446). He is also a co-designer of HMAC, the widely used message authentication and pseudo-random function. More recently, he designed HKDF, an extraction-based key derivation function that is becoming a standard for key derivation and has already been incorporated into protocols such as TLS 1.3, Signal, WhatsApp, Facebook Messenger and more.

Other influential designs include: the SIGMA key-exchange protocol, a cryptographic basis for IKE and now for TLS 1.3; HMQV, one of the fastest provably secure and versatile key exchange schemes; threshold and proactive systems for encryption, signatures and passwords; state-of-the-art protocols for searching on encrypted data; and powerful password-based protocols for authentication and data protection. Hugo has also contributed to the theoretical foundations of cryptography through the study and advancement of notions such as pseudorandomness, zero-knowledge, secure communications, distributed cryptography, and more. He believes that, contrary to some popular adages, in cryptography, theory is truly practical (and cryptography without supporting theory is, in most cases, bad cryptography).

Hugo holds a Ph.D. in Computer Science from the Technion and has authored more than 100 publications with over 23,000 citations. He is an Associate Editor of the Journal of Cryptology, a Fellow of the International Association of Cryptologic Research (IACR), an IBM Fellow, and a member of the IBM Academy of Technology.

Hugo is the recipient of the 2015 RSA Conference Award for Excellence in the Field of Mathematics, the 2018 Levchin Prize for the development of real-world cryptographic schemes with strong security guarantees and proof, and multiple IBM awards including two corporate awards.
