Hugo Krawczyk is Research Fellow at Algorand Foundation. He has contributed to the cryptographic design of numerous Internet standards, including IPsec, IKE, and SSL/TLS. His SIGMA key exchange protocol serves as the cryptographic basis for both IKE and TLS 1.3 handshake. Hugo is a co-inventor of the HMAC message authentication algorithm and the designer of HKDF, the emerging key derivation standard adopted by TLS 1.3, Signal, WhatsApp, Facebook Messenger and more. He contributed to the theory and applications of pseudorandomness, zero-knowledge, key exchange, password authentication, threshold and proactive cryptosystems, and searchable encryption. Hugo is a Fellow of the International Association of Cryptologic Research (IACR), 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, and multiple IBM awards including two corporate awards. Prior to joining the Algorand Foundation, he was a Distinguished Research Staff Member and an IBM Fellow at IBM Research.
