Moti Yung is a computer scientist whose main interests are in cryptography, security, and privacy. He is currently with Snap Inc, and he is a Fellow of ACM, IEEE, IACR, and EATCS. He earned his Ph.D. from Columbia University in 1988. He worked at IBM Research, was a vice president and chief scientist at CertCo, was a director of Advanced Authentication Research at RSA Laboratories, and a research scientist with Google. He has been holding adjunct faculty appointments at Columbia where he has co-advised several Ph.D. students over the years. He also served as a consultant to leading companies and to open projects with various governments. Yung's major interests are building useful foundations for the field based on practical needs, and transforming theoretical ideas into practice. He has contributed extensively to theoretical cryptography (examples: innovating the notion of public key cryptosystems secure against chosen-ciphertext attacks, foundations of signature schemes, and mobile adversary in secure computing protocols). He has, further, contributed to innovative secure industrial technology within actual large scale systems. Examples of the latter are: IBM's SNA network authentication, the Greek National Lottery system, the security and privacy aspects of Google's global systems such as the Ad Exchange (ADX) and the ephemeral ID efforts for Google’s BLE beacons, and Snap’s ``my eyes only memories’’ cloud security. Finally, his interest in cybersecurity has led to inventing Cryptovirology and its attacks, which, first, predicted ransomware and alerted about it, and, secondly, conceived the notion of Kleptography: a deniable algorithm substitution attacks on cryptosystem, which was allegedly mounted within the deployed American Federal Information Processing Standard detailing the Dual_EC_DRBG.
