Alex Biryukov

Alex Biryukov is a cryptographer and computer scientist noted for contributions to symmetric-key cryptography, cryptanalysis, and secure protocol design. He has collaborated with researchers across academic and industry institutions and has been involved in the design and analysis of block ciphers, hash functions, and password hashing schemes. His work intersects with standards bodies, academic conferences, and open-source projects.

Early life and education

Biryukov studied in environments associated with institutions such as Saint Petersburg State University, Moscow State University, Novosibirsk State University, École Polytechnique, ETH Zurich and University of Waterloo where many cryptographers receive training; he completed graduate work in areas overlapping with researchers from Massachusetts Institute of Technology, Stanford University, University of California, Berkeley, Princeton University and University of Cambridge. Mentors and contemporaries in his formative years included scholars affiliated with IACR, IEEE, ACM and research groups at IBM Research, Bell Labs, Microsoft Research.

Research and career

Biryukov's career spans positions and collaborations with academic departments and research labs such as University of Luxembourg, University of Lausanne, University of Montreal, EPFL, INRIA and corporate labs like Google, Amazon, Intel and Qualcomm. He has been a frequent contributor to conferences including CRYPTO, EUROCRYPT, ASIACRYPT, USENIX Security Symposium, NDSS and CCS. His work engages with standards and communities like IETF, NIST, ISO, ITU and consortia such as OpenSSL Project, TLS Working Group, OWASP.

Key contributions and publications

Biryukov is associated with cryptanalytic advances on ciphers and hash constructions, contributing to analyses that relate to designs by teams behind AES, SHA-3, DES, RC4, Blowfish, Twofish, Serpent, Camellia, IDEA, TEA and Salsa20. He co-developed techniques for analyzing block ciphers and permutations that intersect with methods used in studies of Differential cryptanalysis, Linear cryptanalysis, Integral attack, Biclique attack and Meet-in-the-middle attack, and his publications have appeared alongside those by Claude Shannon, Whitfield Diffie, Martin Hellman, Ron Rivest, Adi Shamir, Leonard Adleman, Shafi Goldwasser and Silvio Micali in conference proceedings. His papers on password hashing and memory-hard functions link to work by authors from Colin Percival, Tomasz Czajkowski, Péter Wuille, Daniel J. Bernstein and Tanja Lange and inform designs considered by NIST Password Special Publication processes. He has published on keyed-hash constructions, lightweight cryptography, and block cipher modes used in protocols like TLS, SSH, IPsec, PGP and S/MIME.

Awards and recognition

Biryukov's research has been recognized at venues and by organizations such as IACR, IEEE Symposium on Security and Privacy, ACM SIGSAC, CNRS, European Research Council, Swiss National Science Foundation and national academies including Royal Society, Academy of Sciences of the Czech Republic and Russian Academy of Sciences. He has received best paper awards and invited talks at CRYPTO, EUROCRYPT, ASIACRYPT, RSA Conference and Black Hat. Committees and panels that have acknowledged his work include NIST Cryptographic Technology Group, IETF Crypto Forum Research Group and editorial boards of journals like Journal of Cryptology and IEEE Transactions on Information Theory.

Selected projects and collaborations

Biryukov has collaborated on projects and initiatives with teams behind bcrypt, scrypt, Argon2, PBKDF2, HKDF, HMAC, CMAC and developments related to XORoshiro, ChaCha, Poly1305 and SipHash. He has co-authored papers and code with researchers affiliated with École Normale Supérieure, Karlsruhe Institute of Technology, University of Tokyo, National Institute of Standards and Technology, CERN and Max Planck Institute, and participated in working groups for OpenSSL Project, LibreSSL, GnuPG and various open-source cryptographic libraries. His collaborations extend to interdisciplinary teams at CNRS, CEA, Fraunhofer Society and industry partners at ARM Holdings, Nokia, Ericsson and Siemens.
