Eli Biham is an Israeli cryptographer and cryptanalyst, currently a professor at the Technion - Israel Institute of Technology Computer Science department. Starting from October 2008 and till 2013, Biham was the dean of the Technion Computer Science department, after serving for two years as chief of CS graduate school.
Biham received his Ph.D. for inventing differential cryptanalysis, while working under Adi Shamir. It had, it turned out, been invented at least twice before.
