Eli Biham
Eli Biham 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 differential cryptanalysis, for which he received his Ph.D., while working under Adi Shamir.
Contributions to cryptanalysis
- 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 the ANSI X9.52 CBCM mode
- Breaking the GSM security mechanisms
- Co-invention of related-key attacks.
- Differential Fault Analysis - joint work with Adi Shamir
- Conditional Linear Cryptanalysis - joint work with Stav Perle
- Efficient slide attacks with reduced time complexity
New cryptographic primitives
- Serpent, a block cipher which was one of the final five contenders to become the Advanced Encryption Standard
- Tiger, a hash function fast on 64-bit machines, and
- Py, one of a family of fast stream ciphers.
- SHAvite-3, a hash function which was one of the 14 semifinalists in the NIST hash function competition.
