Selected Publications

Coming Soon... (but may take some time... well....)
Meanwhile.. Partial Publication list

A Book

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

The book exposes threats that 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).

Research Interests
