Mordechai M. (Moti) Yung is an Israeli-American cryptographer and computer scientist with an extensive industrial research career.

Yung earned his Ph.D. from "Columbia University in 1988 under the supervision of "Zvi Galil.[1] In the past, he worked at the "IBM "Thomas J. Watson Research Center, was a vice president and chief scientist at "CertCo, was director of Advanced Authentication Research at "RSA Laboratories, and more recently worked at "Google and "Snap Inc.[2]. In parallel to his work in industry, he has also held adjunct and visiting faculty appointments at Columbia through which he advised several Ph.D. students (see [1]) including "Gödel Prize winner "Matthew K. Franklin, and "Jonathan Katz.


Scientific and Technical Contributions[edit]

Yung's contributions span a broad range of areas, from theory and foundations of cryptography and related areas, via systems security basic new notions and mechanisms, to actual industrial innovations contributing to the frontier of technology advancement and development.

Trust and Novel Attacks:

Basic Research and Foundations:

Yung has contributed extensively with numerous coauthors to the foundations and theory of basic cryptographic systems and protocols, and co-invented notions, constructions, and systems, some of which are very closely related to and influenced the practice of concrete cryptography and secure and private systems.

Industrial Contributions:

In addition to his extensive scientific contributions in basic and applied research, Yung has spent a career in industry working with engineers, developers, business experts, and other scientists, and concurrently contributed over the years to numerous innovative real-world constructions. These have led to practical implementations that were, in turn, deployed as part of actual systems and networks. His industrial contributions have enhanced the security and privacy of businesses infrastructure, and enabled new concrete applications. These include the following :

Systems Security, Privacy, and Anonymity Research:

Yung worked on software systems security [89][90][91] and further characterized the adversary to consider against software systems that are given to users, calling it MATE: `Man-at-the-End' attack (which became popular in the software obfuscation community[92]). Yung has contributed to anonymity and privacy as well, working on cryptographic anonymous credentials such as "Group signature,[93][94][95] as well as group encryption protocols.[96][97] Yung together with Adam L. Young cryptanalyzed the Reduced-Seat Buses Protocol for anonymous communication.[98] In the same work they broke multiple anonymous communication protocols, such as Taxis, showing that the crucial property of key-anonymity was missing, they further proposed the Drunk Motorcyclists protocol for anonymous communication and proved that it is cryptographically secure.
