I am with Google

At Columbia University, Computer Science: I have held various appointments such as: Adjunct Professor, Visiting Senior Research Scientist.

I am a computer scientist, cryptographer and information security researcher.

From 2007 till early 2016 and from Mid 2018 I have been with Google Inc.

Previously: I have been an Industry Consultant, working on information security and cryptography,
including Research Scientist, Snap (2016-2018); Director, Advanced Authentication Research at RSA Laboratories.

Previously: I have been VP, Chief Scientist, with CertCo
which is formerly: Bankers Trust E-Commerce (BTEC)).

Previously: I have been with IBM T.J. Watson Research Center,

Ph.D. -- Columbia University, Computer Science.

A Book

Malicious Cryptography: Exposing Cryptovirology
A content
by Adam Young and Moti Yung
Published by John Wiley & Sons.

The book exposes threats that show how Cryptography can be used as an attack mechanism, which result from combining strong cryptography with malware to attack information systems. Attacks are presented that pit cryptography against cryptography itself by maliciously utilizing cryptographic algorithms to attack implementations of cryptosystems (called kleptographic attacks). The book also details defenses against these types of attacks. This new and unorthodox use of cryptography exploits modern cryptographic notions, constructions, and tools as "dark side" mechanisms (i.e., as methods that increase threats, and perhaps paradoxically, reduce overall system security).
