Victor Shoup is an internationally recognized expert in the field of cryptography. He is a Professor of Computer Science at NYU and a regular visiting scientist at IBM Research.

Shoup is a Fellow of the IACR (the International Association for Cryptologic Research), recognized for fundamental contributions to public-key cryptography and cryptographic security proofs and for educational leadership. He is the author of over 60 research papers, most of them in the field of cryptography,including public-key encryption, digital signatures, interactive protocols, and fully homomorphic encryption.He is the author of a widely used textbook on computational number theory, published by Cambridge University Press, and is the co-author of a forthcoming textbook with Dan Boneh on cryptography.

Shoup is co-inventor of the Cramer-Shoup cryptosystem, which was the first practical public-key encryption scheme that is provably secure against a chosen ciphertext attack — security of against this type of attack is recognized as essential for most applications. He is the author of NTL, a widely used software library for high-performance number theoretic computations.

For his work on NTL, Shoup received the 2015 Richard D. Jenks Memorial Prize for Excellence in Software Engineering Applied to Computer Algebra (other winners include Stephan Wolfram for WolframAlpha and Mathematica, John Cannon for Magma and Cayley, and the Maple Project at the University of Waterloo). Shoup is also the co-author (with Shai Halevi) of HELib, a widely used software library for performing computations on encrypted data (homomorphic encryption).
