Eli Biham ({{langx|he|אלי ביהם}}) is an Israeli cryptographer and cryptanalyst who is a professor at the Technion - Israel Institute of Technology Computer Science department. From 2008 to 2013, Biham was the dean of the Technion Computer Science department, after serving for two years as chief of CS graduate school.

Biham invented (publicly) differential cryptanalysis,{{Cite web|url=https://www.iacr.org/fellows/2012/biham.html|title=Eli Biham, 2012 IACR Fellow|website=www.iacr.org}} for which he received his Ph.D., while working under Adi Shamir.

Contributions to cryptanalysis

{{prose|section|date=December 2023}}

  • Differential cryptanalysis - publicly invented during his Ph.D. studies under Adi Shamir
  • Attacking all triple modes of operation.
  • Impossible differential cryptanalysis - joint work with Adi Shamir and Alex Biryukov
  • Breaking (together with Lars Knudsen) the ANSI X9.52 CBCM mode (few days before the final standardization)
  • Breaking the GSM security mechanisms (with Elad Barkan and Nathan Keller)
  • Co-invention of related-key attacks.
  • Differential Fault Analysis - joint work with Adi Shamir
  • Conditional Linear Cryptanalysis - joint work with Stav PerleBiham, E., & Perle, S. (2018). Conditional Linear Cryptanalysis – Cryptanalysis of DES with Less Than 242 Complexity. IACR Transactions on Symmetric Cryptology, 2018(3). https://doi.org/10.13154/tosc.v2018.i3.215-264
