Orr Dunkelman (Hebrew: אור דונקלמן) is an Israeli cryptographer and cryptanalyst, currently a professor at the University of Haifa Computer Science department.[1] Dunkelman is a co-director of the Center for Cyber Law & Privacy at the University of Haifa and a co-founder of Privacy Israel, an Israeli NGO for promoting privacy in Israel.[1][2]

Biography

Dunkelman received all his degrees at the Technion - Israel Institute of Technology. He received his Ph.D. degree at the age of 25, under the supervision of Eli Biham.[3] Before joining the University of Haifa, Dunkelman held post-doctoral positions at KU Leuven, at École normale supérieure, and at the Weizmann Institute of Science.[1]

Contributions to cryptanalysis

Among his contributions to cryptanalysis are:

New cryptographic primitives

Dunkelman has taken part in the design of several new cryptographic primitives:

Awards and honors

Dunkelman received the Krill Prize from the Wolf Foundation in 2014, and papers he co-authored won the Best Paper Award at the Crypto conference (2012) and at the Fast Software Encryption (FSE) conference (2012).[12][4]
