Cryptography research deals with theoretical questions and algorithms necessary for secure communications over untrusted channels. Cryptography researchers work on theoretical foundations and practical algorithms for a variety of communication tasks, including authentication (proving one's identity), confidentiality of messages, data integrity and other. With rapidly spreading use of the internet for many critical tasks, from financial transactions to medicine, reliable cryptographic techniques are increasingly essential for communication.

Yevgeniy Dodis is primarily interested in cryptography. His current primary research directions are cryptography based on imperfect randomness, exposure-resilient cryptography, cryptography with biometrics and other noisy data, hash functions and random oracle model and information-theoretic cryptography. Recent achievements include design of special purpose randomness extractors for imperfect sources, formal model of cryptography based on noisy data, design and formalization of intrusion-resilient cryptosystems and new criteria and techniques for design of hash functions.

Victor Shoup's research areas are cryptography and computational number theory; he is especially interested in the interactions between these two areas. He designs and analyzes cryptographic primitives and protocols with security properties that can be proven based on clear and reasonable assumptions, and which are nevertheless practical enough to use in the real world. Most recently, he has been working on practical secure deniable protocols (i.e., participants in an exchange using this protocol can deny that it ever took place) based on novel and use of number-theoretic algorithms.
