Eli Biham
Eli Biham is an Israeli cryptographer and cryptanalyst. He received his Ph.D. for inventing (publicly) differential cryptanalysis, while working under Adi Shamir. It had, it turned out, been invented at least twice before. A team at IBM discovered it during their work on DES, and was requested/required to keep their discovery secret by the NSA, who evidently knew about it as well.
Eli Biham is currently a professor at the Technion Israeli Institute of Technology Computer Science department.
